Zelas Gort

水母召（ゼラス・ゴート） This spell was created to summon jellyfish. When drowning in the sea, the caster can be saved by the rush of jellyfish, but no other use of this spell can be seen. (Though jellyfish do taste quite good, pickled.) In the novels, can only be cast by Naga, who has a special affinity with jellyfish, but in the anime Lina and others can also cast the spell.
