Visage is the most powerful enemy on the first tier, but it still is not very dangerous. It uses Sapping Strike, which inflicts Sap, and Reverse Polarity to shift the party's rows. After its HP falls to 10,240, Visage begins to use Dread Gaze, inflicting Petrify. If both of Visage's allies are dead when it is killed it uses Quake, which is somewhat dangerous, though avoidable with Float. It can also be bypassed if Visage is not killed last. Casting Firaga or throwingFlametongues works well to hit his weakness to Fire attacks.
Visage's weakness to Fire attacks may further reinforce the possibility that he, like the other tiers of the final boss battle, was inspired by Dante Aligheri's Divine Comedy. Specifically, Visage resembles Satan in appearance; in the ninth circle of hell, Satan was depicted as a demon entrapped up to the waist in ice, which may explain Visage's weakness.
