Bigby’s Battering Gauntlet, 4th level Evocation spell.  (Jeff Easley from AD&D Greyhawk Adventures by James M Ward, TSR, 1988)  “Spells like Drawmij’s Instant Stripping and Otto’s Gelatinous Cube Transformation to Edible Gel have been left off as too esoteric for even the most curious spell crafter.”
