Fist of Aten(アテンの拳Aten no Kobushi) is "Mobilizer of Ceremonial Equipment" Khamsin Nbh'w's Unrestricted Spell. It is essentially a rocket punch from a hand that has been detached from Rubble Giant. The hand ejects flames from its end, allowing it to fly. When the detached hand hits the target, it causes a big explosion because of its mass and velocity. The hand has enough power to severely crush the top of Seireiden's Crypta from within.
