Ozma has two main phases; the earlier right-hand ending branch adds a third duel.

His principal attacks are listed below.

Attack ①:

Two slashes lead into a charged weapon plunge and a large explosion around him. Time your dodge for the blast.

Attack ⑦:

A wide attack first pulls you toward him without damage, then charges a large blast. Walk clear during the long wind-up.

These cover the main first-phase attacks.

Depleting the first health bar triggers the second form.

Attack ②:

A shockwave with a very obvious charge. Dodge at release.

Attack ③: healing crystal. Ozma summons a purple crystal in front of him and prepares to absorb it to restore health. Switch attention to the crystal and destroy it rather than attacking only the boss. The crystal emits area pulses: dodge the outward energy wave, then resume attacking it instead of committing through the pulse.

Attack ④:

Three jumping slams drop large spheres nearby. The first two are quicker; the third has a longer charge and ends in a surrounding explosion. Retreat early.

Attack ⑤:

He flies up, fires projectiles and finishes with an explosive slam. Stay clear of the landing.

Defeating the second phase grants the Lord of Chaos Scroll.

If you chose the earlier right-hand ending branch, complete a third duel as well.
