Moldarach (Sandship)

You'll find yourself in a large chamber within the Lanayru Mining Facility. Moldarach, a massive scorpion, will emerge from the sand.

Moldarach has two main attacks: it can either scuttle across the floor quickly or slam its tail down. When it scuttles, try to stay out of its path. When it slams its tail, it will create shockwaves, so jump over them.

Your primary tool here is the Gust Bellows. Use it to blow away the sand covering Moldarach's eyes. When its eyes are exposed, it will become stunned.

While it's stunned, quickly run up to it and attack its eyes with your sword. You can also use the spin attack for more damage.

After you've attacked its eyes a few times, Moldarach will recover and start attacking more aggressively. It will also start using its pincers to try and grab you.

When Moldarach tries to grab you with its pincers, dodge out of the way. If it successfully grabs you, you'll take damage.

Moldarach will eventually flip over onto its back, exposing its soft underbelly. This is your chance to deal massive damage. Run up and attack its underbelly with your sword.

Repeat this process: use the Gust Bellows to stun it, attack its eyes, dodge its attacks, and then attack its underbelly when it flips over.

Once you've depleted its health, Moldarach will be defeated.
