Yiazmat has well over 50 million hit points. This astronomically high number is the main reason he takes so long to kill, since regular attacks break the damage limit only in the International Zodiac Job System version. The player can accept the hunt for Yiazmat after vanquishing the Hell Wyrm and all Rank VII Marks except Shadowseer. In the International Zodiac Job System version, Yiazmat is fought at Trial Mode on stage 98. The party will face Yiazmat with less HP.
