The Valigarmanda has high Defense and cannot be harmed physically, except with weapons that ignore Defense like the Valiant Knife, Fixed Dice, Drill, and Ultima Weapon. It is also immune to all elements except Fire. Therefore, the party should cast Fira and Firaga spells repeatedly to melt the esper's prison of ice. Offensively, Valigarmanda's only damaging spell is Blizzaga, which is weak, so defeating it is a simple task.
[view·edit·purge]In fiction, an esper (stylized as ESPer) is an individual capable of telepathy and other similar paranormal abilities. The term was apparently coined in this sense by Alfred Bester in his 1950 short story "Oddy and Id" and is derived from the abbreviation ESP for extrasensory perception.
