Garufor Kirestal (氷獣結晶陣 Garuforu Kiresutāru, lit. "Ice Beast Crystal Formation") is an attack Sinbad uses in his Djinn Equip with his Djinn Valefor. Sinbad freezes his opponent inside a stalactite of ice which knocks them out.
When AoS Night 53 was originally published on UraSunday's website, the kana for the first word in this attack were printed ザルフォル Zaruforu. This was altered to ガルフォル Garuforu when the chapter was published in volume 7.
