Yiazmat is the ultimate Elite Mark in Final Fantasy XII. He is not only the ultimate mark, but also the ultimate boss. 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 Zodiac versions.
