Ice Gigas

It serves as one of the bosses in the Tower of Mysidia, guarding the spell Ultima. Firion, You, and his allies must defeat it on their way up the tower. He later appears as a random encounter in Pandaemonium's secret room. The Ice Gigas has higher stats than his cousin, the Fire Gigas, but the Fire-type weapons the party should have picked up on the second and third floors of the dungeon will give an edge in this encounter. Casting Blink and Protect helps. The Ice Gigas uses physical blows, punctuated by a few Blizzard 16 and Boulders 9 spells.
