Zelas Gort

From KanzakaDex

Zelas Gort (Japanese: 水母召, Kanji translation: Water Mother (Jellyfish) Summon/Call, Romanji: zerasu gōto) is a summoning spell. Whether it is a black magic spell that draws power from Greater Beast Zelas Metallium or a simple water shamanistic spell is a subject of debate, as some sources list it as the latter despite its name. The reason is that while Zelas Brid is written with the kanji meaning "beast" and "king" in its original written form, Zelas Gort is written with the kanji meaning "water", "mother" (together meaning "jellyfish") and "Summon" instead.

This spells summons a huge jellyfish, which doesn't seem to be bothered by the lack of water. It seems that the caster has an amount of control over the creature and can use it to immobilize foes.

This spell was only cast by Naga the Serpent in the novels, but Lina Inverse also uses it in Slayers Next, hinting that she learned the spell from her former companion.
