Gu Ru Dooga

Gu Ru Dooga (Japanese: 魔竜吠グ・ル・ドゥーガ, Kanji translation: Demon Dragon Howl, Romaji: gu ru dūga) is an astral shamanistic summoning spell created by Naga the Serpent.

The spell summons a dimos dragon. The caster has limited control over the creature, and additional spells (such as Void Breath) are needed to be cast in order to force the dragon to perform certain tasks.
