Gil Turtle

Gil Turtle, A deadly enemy in early levels, it can be found in two locations: the Gil Cave in Galuf's world, and the merged world's bonus dungeon the Sealed Temple's River of Souls as well as in the Cloister of the Dead. Despite being undead, Raise spells and items have no effect on Gil Turtle due to its Heavy status; it is instead weak to ice. Its attacks include Earthquake, which does heavy damage unless Float is cast, and Turtle, which hits two party members at one turn and can inflict confuse, old, and poison, similar to the Shield Dragon's Knock Silly.  It will also cast Earthquake when defeated. The Death Sickle's instant death effect fully heals the Gil Turtle due to it being undead. The Sealed Temple Gil Turtle will drop a Grand Helm.
