Skyward Sword: How To Beat Thousand-Year Arachnid Moldarach at Lanayru Mining Facility

Updated on January 28, 2012


This hub is going to explain how to beat the Thousand-Year Arachnid Moldarach in The Legend of Zelda: Skyward Sword. Moldarach is the third boss of the game and represents a big step down in difficulty as compared to Scaldera. Even so, you must take great care to defend yourself against the Thousand-Year Arachnid, as his distinct style can catch you off-guard.

As always, I will break down the boss fight into each of its phases and explain them in detail. Read on!

Phase I

In this first phase of the battle, Moldarach will move towards you with both pincers closed. The pincers have eyes which you need to target until the pincer breaks off. Since your Goddess Sword can't penetrate the tough exoskeleton or the armored pincers, you'll have to play the waiting game.

Once Moldarach opens a pincer, he will open it in a vertical or horizontal angle. Much like the Ghirahim fight, you will need to swing your sword to exploit this. For instance, if Moldarach opens his pincer vertically, you need to swing your sword horizontally, and vice versa. After damaging one of Moldarach's pincers, he will attempt to grab you with the damaged appendage.

Tip: You can tell when a pincer is about to attack when its eye turns red.

Backflip to dodge the grab (which does 1 Heart of damage if successful and requires you to struggle with the Wii Remote to break free).

Note: Alternately, you COULD try to Shield Bash the offending pincer, but you'd have to time it perfectly. Dodging is easier.

Repeat this routine a few times until you break the pincer off, which will leave Moldarach with just one pincer. At this time, he'll add a tail whip attack to his repertoire. He broadcasts it by moving his tail to one side, shortly before attempting a sweep on you. The second you see him broadcast it, get ready. As Moldarach starts the sweep, backflip backwards and you should be able to dodge it. Mastering the timing of this sequence is probably the hardest part of the fight. However, Moldarach only uses it once or twice if you press the attack, so failure to dodge it should not be a game-breaker.

Once you break Moldarach's other pincer, he will retreat under the arena's sand, which marks the start of Phase II.

Phase II

In this second phase of the fight, you have to equip your Gust Bellows and blow away the sand present in the arena to expose Moldarach.

Note: You only have to expose the part of the arena where Moldarach is currently located.

Keep an eye out for a giant lump of sand that moves. That is Moldarach. Should you stray too close to the lump, Moldarach will attempt to sting you with his tail (this can be dodged or Shield Bashed). Once you've located the giant arachnid, proceed to use the Gust Bellows to remove the sand.

Moldarach, finding himself exposed, will leap out and...start retreating by walking backwards. This is when you have to rush him and start using thrust attacks with your Sword on his eye. You can kill him within a few blows (perhaps even the first time you expose him), but should you fail to do so fast enough, he will burrow into the sand and force you to expose him once again. Don't worry though: All damage dealt to the eye stays, so you don't have to finish him in one round.


After what probably feels like more of a mini-boss fight than a proper boss fight, Moldarach falls, disintegrating from tail to head (which is a nod to classic Zelda games such as Link to the Past, where most bosses died this way) and leaving a Heart Container for you to collect. Winning this boss fight marks the end of the game's first Phase (the one that has you collecting Ancient Tablets to unlock areas), and the plot will soon thicken as the second Phase starts...

That's about it for this hub. Although there's not much to write about in this particular boss fight, if you feel like I missed something, or want to add tips/tricks, OR want to just talk about Skyward Sword in general (spoilers at a minimum please!), please free to post in the comments section.

Until the next time, take care and have fun! ;)

      For Phase II, when Moldarach attacks with his tail (This happens when you stand still and stare long enough at his remaining eyes. Or trying to attack it but your Wiimote just won't follow your thrusts properly), you can use your Shield Bash to deflect the attack.

      Also, after Moldarach emerges from the sand, you can shoot Skyward Strikes with a thrust. This damages less but will keep you distant from those charge attacks.

      Hope this helps a bit. It's my favorite boss to beat. ^^
