Final Fantasy X Bosses

FFX Strategy Guide for Boss Battles

Final Fantasy X Bosses are usually easy if you over-level, but there are a few challenges. Several FFX bosses have secret Achilles' heels that may surprise you -- for instance, did you know there's one boss that's scared of Auron?

This FFX Boss Strategy guide will help you play the game without having to backtrack or level grind. You'll learn how to achieve overkill, collecting more AP and loot. Be warned: some of these tricks make certain battles too easy!

So here's all the regular FFX Bosses -- ones you absolutely must fight in the storyline -- plus Lord Ochu and Yojimbo. For each one I give vital stats, strategy, and (sometimes) suggested preparations that will make the battle easier.

This page is part of my Final Fantasy X Secrets series.

Keys to this Guide

Numbers in () are the damage needed for overkill.

Numbers separated by / refer to different forms of the boss or phases within the same battle.

I skipped a few stats: Luck because nearly all are 15; one or two are 20; Gil and AP because you're gonna beat 'em anyway, and Bribe because obligatory bosses are not bribable.

"Equipment" "Armor" and "Weapon" mean items that the monster might drop at battle's end.

Silly Final Fantasy Boss Poll - Before we get started, let's review...

It just isn't a Final Fantasy game unless you have a boss battle with...

  • A dancing vegetable (possibly wearing a tutu)
  • A giant with a sword large enough to use for a boat dock
  • A sparking, malfunctioning mech with a vaguely phallic cannon
  • A blue dragon with random mechanical bits and Godzilla breath ray
  • An ominous number counting down over your opponent's head -- or yours
  • A small cute creature with bunny ears or a knife or kitten eyes that KILLS U DED
  • Aggressive architecture
  • Someone wearing pasties, leather fetish gear and/or butt floss
  • A bishie you have to kill three times
  • Decorative wings that obviously don't work; he/it must be using a Float spell

Final Fantasy X Boss: Geosgaeno
Final Fantasy X Boss: Geosgaeno

Boss: Geosgaeno

Submerged Ruins

HP: Lots    Elements: Weak to all four

Immune: All but Poison (Resist: 90%)

MP: 128  Str: 36  Mag: 40  Def: 50  MDf: 50  Agl: 48  Acc: 50

Drop / Steal / Equipment: N/A

Strategy: Thwack twice and run away, run away! Cutscene interrupts after boss takes 90HP, so don't waste a potion.

Final Fantasy X Boss: Klikk
Final Fantasy X Boss: Klikk

Boss: Klikk

Submerged Ruins: Hall

HP:1500 (400)   MP: 5   Elements: Normal

Immune: Sleep, Poison, Sensor, Scan

Str 14   Mag 1   Def 1   MDf 1   Agl 4   Eva 0   Acc 50

Drop: Ability Sphere   Steal: Grenade(s)   Equipment: None

Notes: I think Klikk's HP may reset to full when a new ally joins the battle.
Strategy: Hit and heal, hit and heal. Ally steals and tosses grenades (each time you steal, chance of another steal drops). If you want the overkill, delay until ally's overdrive builds, then Mix Grenades x2.

FFX Boss: Tros
FFX Boss: Tros

Boss: Tros

Underwater Ruins - after diving from Salvage Ship

HP: 2200 (600)   MP: 10    Elements: Normal

Immune: All status effects except...

Vulnerable: All Breaks, Slow, Sleep, Scan, Delay

Str 0   Mag 1   Def 1   MDf 1   Agl 12   Eva 0   Acc 20

Drop: Power Sphere   Steal: Grenade   Equipment: None

Special Attacks: Nautilus Charge whole party for ~150HP, Tentacles ~100HP
Prep: For overkill, fight extra pirhanas first to charge Rikku's overdrive a bit.
Strategy: Steal grenades and throw them when it goes to far side of room. Heal when HP drop below 200. After its second retreat, use Trigger Command "Pincer Attack". Cheer helps increase damage.

Boss: Sin Fin SS Liki
Boss: Sin Fin SS Liki

Boss: Sin's Fin

From the Ill-Fated S.S. Liki

HP: 2000 (1000)   MP: 100   Elements: Normal

Immune: All status effects except Delay/Sonic Wings

Vulnerable: All Breaks and Scan, Sensor, Demi

Str 1   Mag 1   Def 1   MDf 1   Agl 6   Eva 0   Acc 50

Drop: Mana Sphere   Steal: Can't

Weapons/Armor: Piercing, Icestrike / Elemental wards

Notes: Endless Sinscales - 390HP, 200 overkill - means endless AP and up to 99 Power Spheres.
Strategy: Use Tidus' Cheer 3-4 times until you're killing Sinscales with one hit. Bash them until you get bored. Then use Kimahri's Lancet, Wakka's ball and Lulu's spells to hit Sin. When it's below 1000, charge Valefor's overdrive with Sinscales and then have her overkill Fin.
Tip: Heal Wakka and Tidus before finishing this battle.

Kimahri Leveling Tip

Start Kimahri towards Rikku's path to give him Steal and Use very early (guy in very first Agency gives you a Lvl 1 Key sphere; you get 2 for pushing Chocobo Eater off cliff, or lots in Operation Mi'ihen.)

You'll then have a Thief/Alchemist long before Rikku arrives, and he can steal Petrify Grenades from Basilisks in Djose. They are very useful against Guado.

FFX Boss Sinspawn Echuilles
FFX Boss Sinspawn Echuilles

Boss: Sinspawn Echuilles

Moron overboard!

HP: 2000 (400)   MP: 20    Elements: Normal

Immune: Sleep, Petrification, Zombie, Death, Provoke

Vulnerable: DARKNESS, Poison, Breaks, Slow, stuff you don't have yet

Str 10   Mag 15   Def 1   MDf 1   Agl 5   Eva 0   Acc 15

Drop: Ability Sphere   Steal: None

Weapons/Armor: Piercing, Waterstrike / Water Ward

Special Attacks/Notes: Every third turn, "Blender" does ~ 110HP damage to party.
Prep: When you first get on S.S. Liki, kick suitcase in hold for potions! (Not essential, just handy)
Strategy: Wakka's Dark Attack makes "Blender" miss and lasts 3 turns. Tidus' Cheer 5 times boosts defense and strength enough for a probable overkill; or wait to charge overdrives.

Final Fantasy X Boss: Lord Ochu
Final Fantasy X Boss: Lord Ochu

Boss: Lord Ochu

Kilika Forest

HP: 4649 (800)   MP: 39    Elements: Fire-Weak

Immune: Darkness, Poison, Provoke

Vulnerable: Everything else, including Valefor's Sonic Wings/Delay

Str 15   Mag 23   Def 1   MDf 1   Agl 8   Eva 0   Acc 10

Drop/RareDrop: MP Sphere / HP Sphere   Steal: Potion
Bribe: 92,980 Gil for Remedy x80

Weapons: 1-3 of Piercing, Poisontouch, Str +5%, Mag +5%

Armor: 1-3 of Darkness/Silence/Sleep/Stone/Confuse/Berserk Ward

Special Attacks: Poisontouch, EARTHQUAKE to party when it wakes up.
Prep: Charge Valefor's overdrive with random battles, chat up Luzzu for Antidotes, and SAVE.
Strategy: Lulu's Fire does bulk of work. After Ochu falls asleep, it regens, so summon Valefor to hit it; she's immune to Earthquake. Then Dismiss her and bring her back in when he drops below 1200 for sure overdrive/overkill and rare spheres.
Notes: 40 AP (60 for overkill) means be sure to swap in everybody. You could wait until after you get Ifrit from Kilika Temple to use his Fire, but if you beat Ochu on the way, Luzzu and a few Crusaders in woods give extra items.

Final Fantasy X Boss: Sinspawn Geneaux
Final Fantasy X Boss: Sinspawn Geneaux

Boss: Sinspawn Geneaux

Steps of Kilika Temple

HP: 3000 (900)   MP: 30    Elements: Fire Weak; Absorbs Water

Immune: Sleep, Petrify,Dark, Poison, Zombie,Death,Provoke,Doom,Demi

Vulnerable: Silence, Slow, Delay/Sonic Wings, All Breaks

Str 15   Mag 10   Def 1   MDf 1   Agl 7   Eva 0   Acc 100

Drop: Power Spheres   Steal: Nothing

Weapons/Armor: 1-2 slots: Piercing, Darktouch/Dark Ward

Notes: Geneaux starts out ARMORED, nearly impregnable to phys damage, and its two tentacles - 450HP (500 overkill!) - absorb magic.
Special Attacks: Sigh (Mag damage to party), Staccato (Phys dam to party), Venom (dam + Poison to target). Once shell is open, Water and Poison spells.
Strategy: Kill tentacles with physical damage, then swap in Lulu to crack shell. Use Wakka's Silence Attack if you've got it, or Yuna's NullTide. Summon Valefor at 1200 for overkill (She can take a few hits from it to charge up.)

Final Fantasy X Boss: Oblitzerator
Final Fantasy X Boss: Oblitzerator

Boss: Oblitzerator

Luca Dock Four

HP: 6000 (600)   MP: 10    Elements: Lightning Weak; I/W/F Half

Immune: Silence,Sleep,Dark,Pois,Petrif,Zombie,Threat,Death,Provoke,Doom

Vulnerable: Breaks, Slow, Delay, Demi, Scan

Str 16   Mag 10   Def 1   MDf 1   Agl 1   Eva 0   Acc 10

Drop: Elixir   Steal: Can't

Weapons/Armor: 1-2 slots: Piercing, Lightningstrike/Defense +3%

Prep: Buy a few Echo Screens and Eyedrops from O'aka on the way.
Notes: Agility increases each turn. Crane will lower HP to 1/16.
Special Attacks: Blitzball Rush (party damage); often counterattacks with Dark or Silence.
Strategy: Haste Lulu. Have her zap the crane with Lightning 3x to jump start it. (Boy, wish the AAA agent looked like Lu.) Tidus operates crane for amusing/effective damage. Have Lulu Focus 4-5x so she can overkill, or else use her overdrive.

Final Fantasy X Boss: Chocobo Eater
Final Fantasy X Boss: Chocobo Eater

Boss: Chocobo Eater

Mi'ihen Highroad Travel Agency

HP: 10,000 (800)   MP: 5    Elements: Fire Weak  ARMORED**

Immune: Silence,Sleep,Petrify,Zombie,Threaten,Death, Demi,Doom

Vulnerable: DARKNESS, Slow, Delay, 50% resist to Breaks, Poison

Str 25   Mag 20   Def 25   MDf 35   Agl 12   Eva 0   Acc 25

Drop: Lvl 1 Key Spheres ONLY if falls over cliff   Steal: Potion

Weapons: 1-2 slots: Sensor, Piercing, Str or Mag +5% or +10%

Armor: 1-2 slots: Any elemental ward (items ONLY if push over cliff)

Prep: On Highroad to S, Lancet a Dual-Horn so Kimahri has Fire Breath ready.
Notes: **Armored while on feet; knock over or use Piercing weapons. It takes 1201 cumulative dam to knock him over, 501 more to push him back. Lvl 1 Key Spheres if he goes over cliff!
Special Attacks: Push Back whole party + damage; "You're Next" means Fist of Fury (1000HP, 1 target) next turn, Blizzard when on back.
Strategy: Start with Dark Attack. Haste Lulu for Fire, Auron for his Breaks. First time he falls over, Focus Lulu and Cheer to buff attacks. It's hard to push Eater off cliff before killing him: cheat by healing him! You can overkill with Ifrit, but I'm not sure you get the key spheres without pushing him off cliff.

Final Fantasy X Boss: Sinspawn Gui
Final Fantasy X Boss: Sinspawn Gui

Boss: Sinspawn Gui

Operation Redshirt, I mean, Mi'Ihen

HP: Body - 12,000 first battle/6,000 second (800)   Head - 4000 / 1000 (800)
Arms - 800/800 (500)  MP: 30    Elements: Normal  (Armored)

Immune: All status effects and breaks except...

Vulnerable: Power Break, Provoke, Demi

Str 29   Mag 20   Def 1   MDf 30   Agl 10   Eva 0   Acc 100

Drop: Lvl 1 Key Spheres x3   Steal: Potion

Weapons/Armor: 1-2 of: Piercing, Sleepstrike or -touch/ Sleepproof

Prep: Charge up aeons on way to Command Center and level Lulu to have at least 1 -ara spell.
Notes: Armored arms protect it; Lulu's -aras will lop them off with 1 spell each
Special Attacks: Body alternates between Punch (~600HP) and Demi; Head between Thunder and Venom (500+Poison)
Strategy: Haste Lulu to nail its arms, Auron to Power Break and pound it. Use Wakka's ball or spells to stop head. Use one aeon in each battle for overkill and lots of Key Spheres. In second battle, "ally" will take Lulu's place with -aras. (And no, his overdrive isn't worth waiting umpteen turns to see.)

Final Fantasy X Boss: Extractor
Final Fantasy X Boss: Extractor

Boss: Extractor

Ride ze shoopuf!

HP: 4000 (800)   MP: 10    Elements: Lightning Weak; I/W/F Half

Immune: Dark, Silence, Sleep, Poison, Petrify, Zombie, Doom, Death

Vulnerable: Slow, Breaks, Provoke 50%, Threaten, Delay, Scan, Demi

Str 23   Mag 15   Def 1   MDf 1   Agl 15   Eva 0   Acc 30

Drop: Mega-Phoenix   Steal: Potion

Weapons/Armor: 1-3 of: Piercing, [Element]strike / SOS Nul[Element]

Prep: How nice of O'aka to be selling Lightningstrike weapons on the way here!
Notes: Provoke cancels Depth Charge but increases Str for 2 rounds. 500 damage will also cancel it.
Special Attacks: 2 turns of Aqua Shooter for ~200; on turn 4 does Depth Charge, ~350 + Dark.
Strategy: Haste Tidus and Wakka, Slow the Extractor, and Cheer or try to get 2 lightning hits from Wakka's overdrive to overkill.

Final Fantasy X Boss: Spherimorph
Final Fantasy X Boss: Spherimorph

Boss: Spherimorph

Macalania Woods

HP: 12,000 (2000)   MP: 100    Elements: Variable**

Immune: Scan, Sensor, Slow, Sleep, Silence, Dark, Petr, Death, Provke

Vulnerable: Breaks, Zombie, Demi, Threat (75% resist) Poison (90% resist)

Str 20   Mag 20   Def 100   MDf 1   Agl 15   Eva 0   Acc 30

Drop: Level 2 Key Sphere   Steal/ Rare Steal: Ether/Turbo Ether

Weapons/Armor: 2-3 of: Piercing, [Element]strike / [Element]ward

Prep: Switch to non-elemental weapons. Get Ixion's and Ifrit's overdrive charged. Save.
Notes: **Always vulnerable to one element, it absorbs/heals the rest. Each time it takes magic damage, it phases to a new element at random. Counters physical attacks with current element.
Special Attacks: Press does massive damage to party.
Strategy: Haste Yuna and Lulu, get your Nulls up and Steal. Have Lulu Focus about 4x to increase her power and party's defense. Now bring in someone to poke it with a stick (sword, etc), which causes it to give away its current element. Lulu counters with the opposite. Rinse and repeat.

For overkill and rare spheres, keep running tally of damage in your head, since you can't scan. When it gets down below 2000, use Lulu's -ara Fury or Ifrit's or Ixion's overdrive when it's the right element.

Final Fantasy X Boss: Crawler
Final Fantasy X Boss: Crawler

Boss: Crawler

Lake Macalania, Al Bhed Ambush

HP: 16,000 (4000)   MP: 1    Elements: Lighting Weak, Half I/W/F

Protected by Negator: 1000 HP, 1000 overkill

Immune: All Breaks and status effects except...

Vulnerable: Slow, Scan, Sensor, Delay/Sonic Wings, Demi

Str 25   Mag 30   Def 100   MDf 50   Agl 20   Eva 0   Acc 30

Drop: Elixir   Steal/ Rare Steal: Lunar Curtain

Weapons/Armor: 2-4 of: Piercing, [Element]strike / [Element]ward

Prep: Charge Ixion's overdrive and hope you stole some lightning marbles in Thunder Plains!
Notes: Negator blocks summons and spells -- and Crawler's mana beam! Mana beam takes 4 turns to charge; Negator regenerates 3 turns after being hit. Do the math. :)
Special Attacks: Gatling Gun (damage party), Mana Beam (massive damage to 1), Assault counterattacks spellcasts
Strategy: Haste Rikku and Lulu, Slow the Crawler. Have Wakka knock down Negator. Rikku can use Lightning Gem even while Negator is up. Once it's down, Lulu Thundaras. (You might have Auron Guard her from Counterattacks). If it's about to unleash Mana Beam, bring in Ixion and Shield to soak damage, then have aeon cast Thundara on himself to heal. Ixion's overdrive, Lulu's Thundara Fury, or a Lightning Gem should overkill.

FFX Concept Art: Anima and Seymour as child
FFX Concept Art: Anima and Seymour as child

Boss: Seymour (and Anima)

Macalania Temple Antechamber

HP: 6,000 (1400)   MP: 100    Elements: Normal

Immune: Power Break, Silence, Sleep, Dark, Petri, Zombie, Threaten, Provoke,Demi, Death, Doom, Delay/Sonic Wings

Vulnerable: Slow, Mental/Armor Break, Magic Break (50% Resist) Poison (40% Resist), Scan, Sensor

Str 20   Mag 25   Def 1   MDf 25   Agl 20   Eva 0   Acc 100

Drop/Rare Drop: Black Mag / Special Sphere   Steal/ Rare Steal: Turbo Ether / Elixir   Equipment: 2-4 of: Piercing, Silencestrike/-proof

Notes: Guado Guards are 2000HP kill / overkill and self-heal until you overkill or steal from them.
Talking to Seymour raises Tidus' Str, Yuna's and Wakka's MDef.
After Seymour's down to 3000HP, summons Anima; his HP reset afterwards.
Attacks: S. multicasts ice, lightning, water, fire in that order; after Anima uses -ara spells which HURT.
Strategy: Talk. If available, use Kimahri's Stonebreath, Rikku's Petrify Grenades or Stonestrike weapons to remove guards. Meanwhile Haste Yuna and get up all four Nulls. Once she is ahead of Seymour with Null spells, Auron Magic Breaks and thwacks him until he calls for Mommy.

Mommy is Anima: 18,000 (1400) HP, Holy-weak, immune to all Breaks and Status Effects. The gang will remind you of your new aeon (scroll down in summons menu). Summon her to attack, heal her with Blizzara, or Shield when Anima unleashes overdrive. New aeon's overdrive kills Anima.

Now get back to Magic Break and pounding Seymour; the Nulls you cast earlier will save you from nasty multicasts. It won't take long to kill Seymour; one of your aeons can overkill.

FFX Boss Wendigo
FFX Boss Wendigo

Boss: Wendigo

HP: 18000 (1432)   MP: 32    Elements: Fire-Weak

Immune: Poison,Petrify,Slow,Zombie,Death,Reflect

Vulnerable: Breaks, Threaten,Provoke,Doom,Sleep/Silence/Dark( 20% resist)

Str 40   Mag 1   Def 1   MDf 1   Agl 18   Eva 0   Acc 0

Drop: Power Sphere   Steal/Rare Steal: Hi-Potion/X-Potion

Weapons/Armor: 1-2 of: Piercing, Counterattack/SOS Haste, HP+10%

Prep: Charge Ifrit while fleeing temple
Notes: Guado guards cast Berserk, Shell and Protect on him when killed, UNLESS they're petrified.
Special Attacks: Nasty Counterattack once he drops below 50% HP
Strategy: Remove Guado guards with Stonebreath/Petrify Grenades if possible, or steal their potions then kill them (2000HP; 1432overkill). Try Wakka's Sleep Attack and then tiptoe around beastie while Lulu burns him to a crisp. Auron's Threaten will cancel Berserk, and his Breaks are handy (but will wake Wendigo up). Haste helps, as usual, and Ifrit can deliver the overkill.

FFX Boss Evrae
FFX Boss Evrae

Boss: Evrae

Assault on Bevelle

HP: 32,000 (2000)   MP: 500    Elements: Half Damage all elements

Immune: Armor/Magic Break, Sleep, Silence, Pois, Petr, Zomb, Demi, Threat

Vulnerable: Power Break,Mental Break,50% resist Slow/Dark,Doom(30turns)

Str 36   Mag 30   Def 1   MDf 1   Agl 20   Eva 0   Acc 100

Drop: Black Magic Sphere   Steal: Water Gem

Weapons/Armor: 1-3 of: Piercing, Stonetouch/Stone Ward

Prep: Equip Stone/Poison ward Armor, remove elemental weapons. SAVE.
Notes: Keep away 3 turns and Cid fires missiles. Also, no Poison/physical attacks while away. Evrae tends to cast Slow on Hasted characters.
Special Attacks: Breath Attack in melee does 1000HP to party + Poison; Photon attack at distance not so bad. Swooping Scythes to close in and smack party hard.
Strategy: This battle would be bad if Rikku didn't have Al Bhed potions curing poison and party damage. (Hopefully Kimahri too; I always start him on Rikku's path long enough to get Steal and Use). Start with Auron's Mental Break, then tell Cid to move off. Slow Evrae. Plink Evrae with spells, Wakka's ball, and gems so Cid can get off 3 rounds of missiles. Once Evrae refuses to stay away or Cid's out of ammo, Power Break Evrae and use someone's overdrive to finish Evrae off.

Boss: Isaaru's aeons Spathi Grothia Pterya
Boss: Isaaru's aeons Spathi Grothia Pterya

Boss: Isaaru's Aeons

Via Purifico

I'm not giving the full write-up because they're easy, but Grothia (Ifrit) is 8000 HP and ice-weak, Pterya (Valefor) is 12,000, and Spathi (Bahamut) is 20,000.

Forget Overkill; there's no AP bonus or drops.

Tip: as with any aeon duel, shield when the other aeon's about to overdrive; heal elemental aeons with their element. I use Bahamut vs. Grothia and Pterya, then Shiva dances with Spathi.

P.S. Did you get all the rare spheres in the Via Purifico? Here's a Via Purifico Map with directions on unlocking the teleport puzzle. Finding Lulu adds to Isaaru's cutscene.

P.P.S. This is where I plug my award-winning alternate universe sequel to FFX in which Yuna chooses the Final Summoning. Thirteen years later, Isaaru resumes his pilgrimage with Auron's grudging help.

Final Fantasy X Boss: Evrae Altana
Final Fantasy X Boss: Evrae Altana

Boss: Evrae Altana

Via Purifico

HP: 16,384 (2000)   MP: 500    Elements: Normal  (ZOMBIE)

Immune: Sleep, Silence, Poison, Petrify, Demi, Threaten,Provoke

Vulnerable: Breaks,Darkness/Slow resist 50%,Delay,Doom (30turns)

Str 32   Mag 27   Def 1   MDf 1   Agl 25   Eva 0   Acc 100

Drop: Black Mag Sphere   Steal/Rare: Water Gem/Stamina Spring

Weapons: 1-3 of: Piercing, [Element]Strike, Str+3%,Str+5%

Armor: 1-3 of: Zombie/Stone/Silence/Dark/Sleep/Slow/Poisonproof

Notes: This would be hard, if he weren't a ZOMBIE.
Special Attacks: Stone Gaze, shattering punch, Photon Spray on party
Strategy: Take 20 seconds to ponder: what hurts Zombies? Stumped? Okay, highlight the spoiler (which will spoil this battle forever): Toss 2 Phoenix Downs at it and collect your overkill.

Seymour Natus & Mortibody: Final Fantasy X Boss Battle
Seymour Natus & Mortibody: Final Fantasy X Boss Battle

Bosses: Seymour Natus & Mortibody

Bevelle Highbridge

SEYMOUR: HP: 36,000 (3500)   MP: 200    Elements: Normal 

Immune: Demi, Delay,All Breaks and Status Effects except...

Vulnerable: Poison,Power Break,Provoke (10% resist)

Str 30   Mag 25   Def 1   MDf 1   Agl 21   Eva 0   Acc 100

Drop: 2x Lvl 2 Key Sphere   Steal/Rare: 2x Tetra Elemental

Weapons/Armor: 1-3 of: Piercing, [Element]Strike,/SOS Shell

MORTIBODY: HP: 4000/3000/2000/1000 MP: 50  Elements: Normal 

Immune: Demi, All Breaks and Status Effects except...

Vulnerable: Power Break,Armor Break (50% resist)

Str 22   Mag 20   Def 50   MDf 1   Agl 28   Eva 0   Acc 100

Prep: Run around save sphere beforehand and charge Bahamut's overdrive in random battles.
Notes: When you KO Mortibody, it drains its new max HP from Seymour and regenerates. First it drops to 3000HP, then 2000, then sticks at 1000.
Special Attacks: Mortibody often uses Desperado, major damage to party + Dispel, if anyone's got multiple defensive spells up.
General Strategy: KO Mortibody so it uses its turn to suck HP from Seymour instead of hitting you. If you can put Reflect on Tidus, Provoke Seymour into bouncing his spells off Tidus.


  1. Elemental Phase: Mortibody casts Fire/Blizzard/etc, wiping out the Null for that element, then Seymour multicasts the same element as -ara. Sometimes Mortibody hits party hard with Desperado doing damage + Dispel to cancel Haste, Reflect, etc.
    Strategy: Haste Yuna, get up Reflect if you have it or use Shell/Protect/Lunar Curtain. Have Lulu Bio Seymour so he's taking damage every turn. Talk to increase Strength or Mag Df. Steal from Seymour. Power Break and pound Mortibody as your primary target, Seymour with area spells/attacks/overdrives. Also cast Reflect on Seymour.
  2. Petrify Phase: When Seymour drops below 24,000 HP, he Protects himself (or you if you Reflected him), then starts casting Break which petrifies 1 character.
    Strategy: Un-petrify with Al Bhed Potions and/or "kill" Mortibody before it uses Shattering Claw, which not only removes a petrified character from battle, but won't let anyone take his/her place! Keep pounding Mortibody as primary target, or do area attacks.
  3. Flare Phase: When Seymour drops below 12,000, he starts casting Flare for 2000-2500HP damage on one target.
    Strategy: Reflect will save you. Mortibody casts Cura on Seymour or on party if you've put Reflect on Seymour. Bring in aeons with overdrives ready when he gets below 5,000 (or below 10,000 if you've got Bahamut ready).

Final Fantasy X Boss: Defender X
Final Fantasy X Boss: Defender X

Boss: Defender X

Far side of Calm Lands

HP: 64,000 (4060)   MP: 1   Elements: Normal   ARMORED

Immune: Power Break, Status Effects except...

Vulnerable: Provoke,Dark (resistant), Armor/Mental/Magic Break, Doom(10)

Str 42   Mag 5   Def 30   MDf 1   Agl 20   Eva 0   Acc 0

Drop: Lvl 2 Key Sphere   Steal: 4x Lunar Curtain

Weapons: Piercing, Str or Magic +3/5/10%   Armor: SOS Protect

Notes: Armored so only piercing weapons do much. Mighty Guard (Protect, Shell, Nulls) when critical.
Special Attacks: Blast Punch halves target's HP; Haymaker major damage to one target; SlowgaPrep: An aeon or two in overdrive. Aspirin and Ben-gay.
Strategy: Hastega, Dark Attack and Protect your party -- this thing's attacks are brutal. Haymaker usually misses if it's blind. If you're really in a jam, Provoke it and it'll just keep Blast Punching Tidus (how satisfying!) which simply halves his HP. Normally, I settle in with Yuna healing Lulu and Auron while they take turns smashing the thing. "Peel the fruit" for Lu with Mental Break. Once Yuna gets charged up for a Grand Summon, Dispel its Mighty Guard and bring in Bahamut.

Final Fantasy X Boss: Yojimbo
Final Fantasy X Boss: Yojimbo

Boss: Yojimbo

Cavern of the Stolen Fayth

HP: 33,000 (4080)   MP: 2000   Elements: Normal  

Immune: All Breaks, all status effects except...

Vulnerable: Doom in 5 turns.

Str 34   Mag 35   Def 80   MDf 1   Agl 32   Eva 0   Acc 0

Drop/Steal/Items/AP/Gil: None

Prep: Charge your aeons' overdrives with Magic Urns on the way in; have aeons plunk them for prizes until they blow up. (if explosion kills aeon, go to aeons menu and improve their Def/HP)
Special Attacks: Daigoro 1 target for 500; Kozuka 1 target for 1000 + Poison and MP drain; Wakizashi 1000 to everyone, and Zanmato = 9999 to party.
Notes: His overdrive Zanmato is almost certainly Game Over unless you bring in an aeon to shield.
Strategy: Hastega and hammer away. Lulu's -agas do plenty damage. If you get frustrated, Doom works, but aeons should trounce him.

Str ½ Biran's   Mag ⅔ Kimahri's   Def 30   MDf 50   Agl Kimahri's - 4   Eva 0  Acc 100  LANCET: Fire/Stone/Aqua Breath, White Wind

[BOTH] Drop: Return/Friend Sphere   Steal: Lvl 3 Key Sphere

Weapons/Armor: 1-3 of Piercing / MP + 40%

Special Attacks: Bulldozer: hits Kimahri but separates them; Each Guards the other when side-by-side, reducing damage.
Notes: Lancet all 4 Ronso Rages from each one of them before killing either; they don't use Ronso Rage after their buddy is down.
Prep: Make sure Kimahri has STEAL ability. Optionally, improve chances of stealing by acquiring Master Thief auto-ability: see below. It's a prize in the Remiem Temple chocobo race.
Strategy: If Kimahri has Use, Chocobo Feather (Haste) will make your life easier. Then start Lanceting all their Ronso Rages: each has four, but Kimahri may already have some. Use Hi-Potions or Al Bhed Potions. Be sure to use an Overdrive EVERY time you Lancet (Mighty G and White Wind to heal are good ones). Finally, Steal many Level 3 Key Spheres from one of them. Each time you steal, chance of stealing goes down, but you can probably get up to five. Once you've stolen all you can from one Ronso, kill him, then Steal the other. Use area attacks like Aqua Breath or Grenades when they're together, or Fire Breath and single attacks when they're apart.

Master Thief

Master Thief increases chances of stealing items, and stealing rare items. Useful against Biran, Yenke and Seymour.

It takes 30x Pendulum to customize armor with this auto-ability.

Get them by opening 4 chests without hitting poles in the Remiem Temple Chocobo Race. (Follow the route below, but skip a chest.)

Mt. Gagazet Prominence, Shortly After Save Sphere

[SEYMOUR] HP: 70,000 (3500)   MP: 512    Elements: Normal

Immune: Demi, All Status Effects / Breaks except...    

Resistant: 50% to Silence, 90% to Poison

Str 30  Mag 15   Def 40   MDf 40   Agl 38   Eva 0  Acc 100 

[MORT] HP: 4000/ 3000/ 2000/ 1000 (N/A)*   MP: 512      Elements: Normal  Immune: All Status Effects, Breaks, Demi    

Str 40  Mag 40   Def 100   MDf 1   Agl 38   Eva 0  Acc 100

[Seymour] Drop: Lvl. 4 Key Sphere   Steal: Elixir

Weapons/Armor: 1-3 of Piercing, Darkstrike / SOS Shell

Special Attacks: (1) Seymour casts Zombie, Mort casts Full-Life to kill 1 target; (2) Seymour casts Reflect on self then Flare; (3) Mort casts Dispel, then Seymour Cross-Cleaves party for 2500 (Defend with Triangle button to halve this), (4) Seymour unleashes magical attack Total Annihilation which kills almost anyone without Shell.
Notes: Kimahri can raise Str with Talk command (not worth it); Yuna can raise her MDef (worth it). Every time you KO Mortichoris, it sucks HP from Seymour. (Its Max HP drop 1000 each KO until it reaches 1000). Seymour Banishes aeons on his turn, so...
Prep: Get all aeon overdrives charged; buy Holy Waters from Wantz. Equip any Silencestrike or Poisonstrike weapons you have; Seymour's vulnerable to those. If someone has Master Thief (see above), steal lots of Remedies from Grats on the way up Gagazet and customize 2-3 people's armor with Auto-med (takes 20). Then they'll cure Zombie status instantly.
Strategy: Poison Seymour, then keep attacking Mortichoris so it's sucking HP from Seymour instead of hitting you! For most of battle, I suggest Tidus to Haste and use Holy Water, Lulu for attacks and Auron because his Piercing weapons can damage Mort or Seymour. Yuna backing up.

1. Hastega to start and cast Bio on Seymour. (Silence may also be useful.)
2. Seymour casts Lance of Atrophy to Zombie a character. Get Holy Water or Remedy on him/her before Mortichoris follows up with Full-Life, which kills a Zombie.
3. Steal, keep trying to Poison Seymour and/or use magic and Rikku's items to KO Mortichoris before....
4. Starting 3 turns in, Mortichoris often casts Dispel on party, then Seymour Cross-Cleaves whole party for ~2500 damage. If Mort casts Dispel, hit triangle so everyone defends against Cross-Cleave.
5. Seymour follows up casting Reflect on self + Flare, killing anyone not healed up. If someone gets a turn before he does, Dispel his Reflect and he'll Flare himself!
6. Also Dispel if Seymour casts Shell, Protect.
7. Keep bashing Mortichoris as primary target with Seymour as secondary (Poison + Mortichoris will be hurting him). Cut loose with aeons, but save Bahamut.
8. GET READY when Seymour starts charging: you'll need everyone with Shell up or else bring in an aeon to block TOTAL ANNIHILATION attack which tends to kill party.
9. Once Seymour's down to 15,000 or so, bring in Bahamut with overdrive to get the overkill.

Peak of Mt. Gagazet

HP: 40,000 (6400)   MP: 256   Elements: Normal  

Immune: Silence,Sleep,Petri,Zombie,Death,Provoke,Doom,Demi,Delay

Resists: Dark (100), Poison (90), Power Break (50), Magic Break (50)

Vulnerable: Slow,Armor Break,Mental Break,Reflect,Threaten

Str 37   Mag 40   Def 100   MDf 100   Agl 32   Eva 0   Acc 50

Drop: Return Sphere   Steal: Turbo Ether

Weapons: Piercing, Half MP Cost   Armor: MP +10%

Notes: This battle would be hard, if not for a secret: this beast is SCARED OF AURON. When Keeper gets below 50% HP, it casts Curaga on self -- or on party, if you put Reflect on it!
Special Attacks: Mana Breath usually kills target (esp. an aeon); Tail Sweep damages party + Delay; Photon Wings damages party + Dark, Poison, Curse (blocks overdrives; cured by Holy Water)
Prep: An aeon or two in overdrive for insurance, Holy Water, and equip any Curseproof, Darkproof, Poisonproof armor you've got.
Strategy: Hastega, Bio the beastie and let Auron rip with Power/ Armor/ Mental Breaks or Banishing Blade while Yuna keeps him alive (sort of). Be aware: Keeper is SMART, and will often counter these with Protect and/or Shell (but this wastes its turn). Likewise, don't cast Slow, or it'll cast Haste. It may Dispel if you cast Reflect on it, but worth it if you can get it to bounce Curaga on you! Aeon overdrives can wittle it down, but it mashes them like bugs.
If you're really in trouble, stop, take a deep breath, and scan through Auron's special abilities. There's one we never use that will turn this thing into a bunny rabbit. (Highlight if stumped: Threaten) It makes this battle far too easy, but proves again that Auron is Made of Awesome.

Zanarkand Dome - Cloister of Trials

HP: 52,000 (8000)   MP: 500   Elements: Normal  

Immune: All (including Demi) except...

Vulnerable: Silence, Mental Break, Provoke

Str 36   Mag 1   Def 100   MDf 100   Agl 36   Eva 0   Acc 8

Drop: Lvl 4 Key Sphere   Steal: Ether/Turbo Ether

Weapons: Piercing, [Element]strike  Armor: [Element]proof

Notes: You'll need aeons charged for next battle, so use them sparingly; however, Valefor dominates this guy because mines can't reach her and she dodges well.
Special Attacks: Sets "Glyph Mines" on platforms at random that blow up a turn later. Berserk Tail causes Berserk (duh). Counterattacks by slashing 3 characters in front of it.
Prep: I recommend charging overdrives for Valefor and Ifrit, but it's not essential.
Strategy: Hastega really helps. Mental Break and hit it with Flare (it's immune to Ultima/Demi). Take your time: keep moving characters behind it and out of the way of mines. Don't let more than one person get Berserked; Esuna/Remedy cures it. Berserk on Auron, Wakka, or Tidus is okay: it makes them stronger. Just Life and Re-Haste them when they go down. You'll probably need an aeon overdrive to kill it. Try Valefor.

Zanarkand, Hall of the Final Summoning

HP: 24,000 / 48,000 / 60,000 (10,000)   MP: 500    
Elements: Weak to Holy

Immune: All but Threaten (75)

Str 20   Mag 30   Def 50   MDf 50   Agl 40   Eva 0   Acc 0

Drop: Lvl 3 Key Shpere   Steal: Mega Potion/Farplane Wind

Weapons/Armor: Piercing, Zombiestrike/Zombieproof

Special Attacks: See Strategy below
Prep: If Yuna's close to Holy on Sphere Grid, go back to Dome and level her up for Holy. Charge aeon overdrives. Equip any Confuseproof armor you have. Silenceproof on mages also a good idea. Holy Water is useful but not essential (steal it from the Y-machinas in Zanarkand). Teach aeons Dispel if you can.

Form 1: Really Big Hair: Warm-up. Don't use aeons. Hastega everyone, Steal, Cheer and use Reflex/Focus to boost defenses. It's not hard to kill this form. She often counters phys attacks with Blind, magic with Silence, and skills with Sleep, so have Esunas, Remedies, or appropriate item ready.

Form 2: Snake Monster: It takes a while to whittle her down -- quicker if Yuna's got Holy -- but save overdrives for last form. Yunalesca starts using Hellbiter on whole party to Zombie them (200 HP damage each). Sometimes she casts Cura or Regen on Zombied characters, hurting them. But wait! Zombie is useful later, so leave tougher characters like Auron in Zombie mode. If Yunalesca casts Regen on them, Dispel it. Have Zombies ready with HP near full before killing this form.

Alternatively, remove Zombie status with Holy Water and watch Yunalesca's HP carefully to summon an aeon to knock off form 2.

Form 3: Medusa EWW: First thing she does is cast Megadeath which will kill anyone who's not a Zombie. Aeons are also immune to Megadeath. Then she casts Curaga, so if there's only one Zombie standing, that will KO him/her. Yunalesca will continue to Hellbiter/Megadeath fairly often, so try to keep a balance of new Zombies who are still at high HP, and weak ones whom you can save with Holy Water. Or just let them KO and resurrect them. Even if you're using aeons, you need a few Zombies in case she kills an aeon and then casts Megadeath.

Her Mind Blast also Confuses + Curses people, stopping their overdrives.

Once you get Form 3, THEN unleash every overdrive and aeon in your arsenal. Yunalesca Curses aeons which disables their overdrive, plus she tends to Osmose HP and MP from them. If you've taught aeons Dispel, they can remove the curse.

Bring in Bahamut for overkill; he's the only thing that can do it unless you've gotten Yuna's or Kimahri's Celestial Weapon to power up Valefor or Ixion.

10K Overkill Made Easier

It's hard to get a 10,000 HP overkill. You need a Celestial Weapon or aeon with Break Damage Limit (Bahamut, Anima, Sisters).

If you power up a Celestial Weapon with a crest, it breaks damage limit for:

Yuna's - Valefor

Wakka's - Ifrit

Kimahri's - Ixion

Lulu's - Shiva

Auron's - Yojimbo

Activate Scan near battle's start to monitor foe's HP so you know when to overdrive.

Final Fantasy X Boss: Sin's Right Fin
Final Fantasy X Boss: Sin's Right Fin

Boss: Sin's Fins

We're attacking... Sin's armpit!?

HP: 65,000 (10,000)   MP: 256   Elements: Normal  

Immune: All but Armor Break, Mental Break

Str 30   Mag 30   Def 100   MDf 50   Agl 20   Eva 0   Acc 0

Left Fin Drop: HP Sphere   Steal: Mega Potion/Farplane Wind

Weapons/Armor: Piercing, Poisonstrike/Poisonproof

Right Fin Drop: Lvl 3 Key Sphere   Steal: X-Potion/Shining Gem

Weapons/Armor: Piercing, Stonestrike/Stoneproof

Notes: 3 boss battles in a row before you rest.

Every fourth turn, fin rests to gather energy; next turn is Gravija.
Special Attacks: Gravija reduces party HP by 1/4; no effect at a distance. Negation, which is a speedy counterattack, removes bad statuses on Fin. ALSO removes good status on you if near.
Prep: Consider powering up 1-2 Celestial Weapons to Break Damage Limit for a couple characters and aeons, to make overkill easier.
Strategy: Hastega, Mental Break, Armor Break, Steal, then pull away. Pound with strongest magic, distance attacks or aeons' special attacks (Heavenly Strike, Impulse, etc). If Rikku has Copycat, copy Lulu's spells or Holy. You can fight close range if that's too slow, but be ready to heal after Gravija before next attack starts dropping people. Replace Hastega after a Negation at close range.

FFX Boss: Sinspawn Genais, Sin's Core
FFX Boss: Sinspawn Genais, Sin's Core

Bosses: Sinspawn Genais, Sin's Core

I don't really want to know which body part this is...

SINSPAWN GENAIS: HP: 20,000 (2000)    MP: 200
Elements: Fire-weak, Water absorbs 

Immune: All Breaks and Status Effects except...

Vulnerable: Power Break,Magic Break, semi-resistant to Silence/Zombie

Str 30   Mag 35   Def 80   MDf 50   Agl 25   Eva 0   Acc 0

Drop: Return Sphere   Steal/Rare: Star Curtain / Shining Gem

Weapons/Armor: Piercing, Zombiestrike, Zombieproof

Sin (Core): HP: 36,000 (3000) MP: 999  Elements: Normal 

Immune: All Breaks and Status Effects except...

Vulnerable: Mental Break,Armor Break

Str 1   Mag 30   Def 100   MDf 100   Agl 20   Eva 0   Acc 0

Drop: MP Sphere   Steal: Stamina Spring

Weapons/Armor: Piercing, Slowstrike/Slowproof

Prep: Get Firestrike weapons and/or Poisonproof armor; remove Waterstrike.
Notes: Sinspawn Genais is in front of Core, keeping party at distance from Core until killed. Genais absorbs magic attacks aimed at Core, heals with Cura, and counters magic attacks with Waterga. When Genais loses half HP, retreats into shell, then armored and immune to Ultima. Core counters attacks on itself (including magic) with low-level elemental spell on all 3 party members.
Special Attacks: Genais mostly poison-based attacks. Inside its shell, uses Sigh, another poison attack, while Core uses Gravija, or may do Toxic Cloud after Gravija which can be deadly.
Strategy: Hastega, Slow Genais so its turn and Core don't have turns back-to-back. Firestrike Genais. Use Silence Buster and Zombie Attack on it if you can; it's resistant to both, but if you get through, that stops Cura. Once Genais is dead, Armor Break core and have at it. "Gathers Energy" means Core will Gravija next turn; bring in an aeon and use Shield to soak it.

Me Engines Can't Take Much More o' This

HP: 140,000 (10,000)   MP: 999   Elements: Normal  

Immune: Demi, All but Armor Break, Mental Break

Str 30   Mag 30   Def 40   MDf 50   Agl 30   Eva 0   Acc 0

Drop: Lvl 3 Key Sphere   Steal: Ether/Supreme Gem

Arms: Piercing, Dark/Sleep/Silence/Slowstrike, Silenceproof

Notes: You must finish battle before Sin's overdrive gauge is full or you DIE.
Special Attacks: Petrifiy/Confuse/Zombie Gaze; after about 16 turns Giga-Graviton overdrive = GAME OVER.
Prep: Break out Stoneproof, Confuseproof, Zombieproof armor.
Strategy: Hastega as usual. Save overdrives/aeons for finishing blow; they waste too much time (again, a quick Scan at the start will let you know when it's within 10K overkill range). Lulu's Doublecast and Rikku's Copycat help a lot, as do Flare, Ultima, Holy. After 2-3 "Sin draws you in" messages, you'll be in hand-to-hand range; Mental Break and Armor Break.

Final Fantasy X Boss: Seymour Omnis
Final Fantasy X Boss: Seymour Omnis

Boss: Seymour Omnis


SEYMOUR OMNIS: HP: 80,000 (15,000)   MP: 999    
Elements: Absorbs or 1/2 dam from elements whose colors are near him

Immune: Demi, Delay,All Breaks and Status Effects except...

Vulnerable: Armor Break, Mental Break

Str 20   Mag 35   Def 180   MDf 100   Agl 40   Eva 0   Acc 0

Drop: Level 3 Key Sphere  Steal/Rare: Shining Gem/Supreme Gem

Weapons/Armor: Piercing, Mag +20%; SOS Shell/Protect/Haste

Prep: You may want Shell or [Element] Eater armor.
Special Abilities:Multicasts element spells 4x per turn, -aga or -ara. Occasionally casts Dispel, then Ultima next turn.
Notes: Seymour has "Mortiphasm" wheels behind him. Red = Fire, Dark blue = Ice, Light blue = Water, Yellow = Thunder. Here's how they work:

  • All 4 same color = multicast -aga of that element, FOUR TIMES.

  • 3 of same color = multicast -aga of that element 3 times, then -ara of the single element.

  • Anything else, he casts -aras for each element.

  • 3x of same color = he absorbs that element; 1-2x, he takes half damage.

  • Attack a Mortiphasm Wheel with a spell to turn it right. Physical attacks turn it left.

Strategy: Hastega, get up Reflect on your party and/or Nulls, bop two of the wheels with low-level spells or Wakka's ball to scramble them. Mental Break and Power Break Seymour, and if all his colors are about to match, bop them again. Or just prep with elemental proof or -eater armor, use Shell and Reflect to soak the damage, and pound him.
Important: Whenever he casts Dispel, gloats, and starts glowing red, he's about to Ultima your ass. Bring in an aeon with Shield to block it.

Braska's FInal Aeon
Braska's FInal Aeon

Boss: Braska's Final Aeon

Inside Sin: Dream's End

HP: 60,000/120,000 (20,000)   MP: 100   Elements: Normal  

Immune: Sleep,Petri,Threaten,DeathSlow,Doom,Demi,Delay,Gravity,Regen

Resists: Silence (75), Poison (90), Zombie (50)

Vulnerable: All Breaks

Str 45/50  Mag 50  Def 100  MDf 100  Agl 40  Eva 0  Acc 10

Drop: None   Steal: Turbo Ether/Elixir

Notes: "Yu Pagodas" floating beside Jecht heal him 1500 points each and may remove status effects. They may be stopped for a few turns with damage (5000K each). Tidus can use Trigger command "Talk" to reset Jecht's overdrive gauge to zero. Works only 2 times, so save it for Jecht's second & final form.
Special Attacks: Jecht Beam causes petrification and character may then be shattered by physical attack; regular sword-swipe hits whole party; Triumphant Grasp hurts and Zombies one character; Jecht Bomber does 4000K to aeon; 2nd form's Ultimate Jecht Shot hits everybody for ~5000K.
Prep: Again, Break Damage Limit for aeons helps. Equip Zombieproof, Stoneproof armor; also Zombiestrike and/or Poisonstrike weapons. Check Rikku's Mixes and see if you've got ingredients for any protect-related buffs like Mighty G.
Strategy: First battle, Hastega, Scan, then use aeons' overdrives. Jecht will clobber them but oh well. Make SURE you remove petrification on any character as they can be Shattered next turn. Between Yuna's turns, get Rikku or others to use Light Curtains or Mixes to Protect party members.
Second half of battle, Hastega, Zombie Strike, Mental Break, then use Ultima to clobber Jecht + Yu Pagodas. Power Break and Armor Break work too, but I think Power Wave removes status effects. Zombie will wear off, but as long as it's on, Yu Pagodas will hurt instead of healing Jecht. TALK TO JECHT with Tidus' trigger command each time you see the "Jecht Overdrive" warning. Use up aeons/overdrives and powerful items you were saving. Doublecast Flare/Ultima/Holy or use Quick Hit.

Grand Finale: Aeons and Yu Yevon

Some people complain this is anticlimactic....

Final Notes: I'm not going to give you a strategy on this one for reasons that will quickly become clear. I will say only this:

if some of your aeons survived Jecht, you might as well do aeon vs. aeon; and remember what you learned about Yu Pagodas in the battle with Jecht. It's still true.

When you're done, pat yourself on the back -- congratulations! -- then go watch this incredibly cool Fan Tribute Video for Auron that gives him the send-off he deserves.

Monster Arena, Penance

Wait! you cry. What about optional bosses, including you-know-what on the HD remaster?

Sorry, I haven't beaten them enough times to have great strategies for them.

I ignored Kimhari the first time through. Then Got to Seymore Flux and got destroyed. I looked at Kimhari, he looked at me and we knew what had to be done. We went back down the mountain. Tails tucked between are legs we met the plains but the fire in our heart was strong. We trained for days. Flans and bassalisks piled ten feet high on all sides.

Soon it wasn't enough. We travelled the world collecting the best critters the future had to offer and when we returned we battled the great monster for fathers of the arena until there was none left. We the reigning champions climbed the mountain again. Our vigor kept us warm and proud on the snowy hillside.

When we encountered Seymore again there was no need to rally the others. They were dismissed. This was between us and him. That battle was swift, a few keen blows felled the blowhard and we returned the people a hero.

@Projectlazy: I love this story. GO KIMAHRI! AVENGE YOUR PEOPLE!

Gaming is even more fun when you expand the story even beyond what the game gives us. Taking on Seymour solo at that point with Kimahri would make it a more meaningful battle. Now I'm tempted to try it again with just him and see if I can make it!
