In The First Berserker Khazan, Ozma stands out as the toughest boss battle due to demanding requirements for the Chains or The First Berserker endings. Not only does this boss have multiple stages, but it’s also immune to most elemental statuses, making it extremely hard to lower its HP without counterattacks or Brutal Attacks. As a mage, Ozma has an impressive array of spells that can potentially kill you in one shot, regardless of your Defense. Prior to being absorbed by Chaos, Ozma fought alongside Khazan to repel and finally vanquish the Berserk Dragon, Hismar. However, to achieve this victory, the mage had to resort to Chaos Magic, which eventually claimed his soul.
