Death Warden

The Allo Ver is a Monster-in-a-box in the game Final Fantasy VI. It casts Doom very frequently, so it is helpful to bring along Gau and have him use the Lich or any other undead Rage. The Lich works best because it can use Fire 2 as its secondary attack, which Allo Ver is weak to. or if it really irritates you, you can just cast raise on it or use some sort of healing item (X-potion, phoenix down etc)
