Chac FFx2

Chac is an optional boss in Final Fantasy X-2, and one of the most challenging enemies your characters face. It appears in both the original Playstation 2 version of the game and the newly-released HD Remaster version on Playstation 3 and 4.

Note: unfortunately, this guide only works for the PlayStation 3 version.

However, an easy way to defeat Chac in the original version was cut in the new version as, perhaps, the creators saw it as too easy. This article explains a step-by-step guide on how to defeat this boss in Cloister 80 of Via Infinito, including information about the monster, dresspheres, garment grids and items you'll need.


Chac can appear in normal or Oversouled form; in Oversouled form, it can't use its most devastating attack, Heaven's Cataract, which deals heavy damage to your characters and usually KOs them. Bringing Chac to Oversoul (by defeating Basilisk characters, and then escaping as soon as they begin to Oversoul) means that this attack doesn't appear on its attack list, making it significantly easier.

HP: 437,850
MP: 820
Strength: 254
Magic: 152
Defense: 88
Magic Defense: 166
Agility: 164
Accuracy: 14
Luck: 0
Evasion: 0
Appearance: Chapter 5

Chac absorbs lightning but is weak against other elemental magic. However, with the following guide you won't need to worry about magic attacks.

Garment Grids and Items

Equip each girl onto the Highroad Winds Garment Grid, as this makes them strike before the enemy. Changes dresspheres within battle can add Slowproof, Stopproof, Haste and SOS Haste. Don't worry about these, though.

Equip your girls with any items that give them auto-haste. A Speed Bangle does this, but if you don't have any, Haste Bangles work too (but only when a character is at critical health). You also may want to consider equipping them with items that give them an immunation against Poison, as in Oversouled form Chac's standard attack poisons the character. Even better, give them items that give them extra MP, reduce the cost of MP, or eliminate MP cost completely. I equipped Paine with Ragnarok (reduces MP cost to zero during battle), and Rikku and Yuna with a Rune Bracer (raises max MP by 100%) and a Gold Hairpin (halves MP cost during battle). Ideally, you'll have three Ragnaroks, but if not, use what you have to ensure your girls have as much MP as possible.


I defeated Chac by equipping each girl as a Warrior. Make sure that they have all learnt the ability Delay Buster. This is where the MP comes in. Delay Buster uses 16 Magic Points each time it's used, so having a lot of MP, or not using any at all, is useful, and reduces the amount of times you have to use an Ether or Megalixer to get your Magic Points back.

Delay Buster greatly delays an enemy's turn. The idea of this strategy is that you delay Chac from ever getting a turn, making it impossible for it to use its deadly move Heaven's Cataract, or freezing move Stony Glare.

Warrior Dresspheres

FFx2 Chac Strategy

Check your characters are all:

  • Using the Highroad Winds Garment Grid.
  • Equipped with a maxed (or nearly maxed) Warrior Dressphere, having learned Delay Buster.
  • Are holding items that gives them extra MP and auto-haste, or the next best thing.
  • Keep Softs, Elixers, Megalixers, Megaphoenixes and other healing items at the top of your list for quick access.

Enter the battle and immediately use Delay Buster with all three characters. As they're on the Highroad Winds Garment Grid, they're guaranteed to attack before Chac does. Keep using this move, and your enemy will never be able to attack.

If a character does run low on MP, get them to use an Elixer on themselves to restore MP. This is risky, as their missed turn for using Delay Buster can give Chac a chance to attack. If this is the case and she uses Stony Glare on one of your characters, quickly heal them with a Soft or a Remedy. If you're fast, your characters will soon all be using Delay Buster again, and won't be interrupted.

This took around ten minutes for Chac to be defeated this way. There are other strategies, but I found this one to be the easiest, and the one that didn't require specific items. Just remember to train all the girls in the Warrior Dressphere (which doesn't take long). Got a faster way to defeat Chac? Did this strategy work for you? Tell us about it in the comments.

I'll give this a try tonight. Benn working on this guy for two days now. I do have to say it's a little annoying that Ribbons and NO accessory protect against Stony Gaze. Heck not even Stoneproof for abilities.
