"At Demogorgon’s enraged command a barrage of lethal bolts, killer forces, and demon-shattering spells were sent to vaporize the insolent figure that rose like a colossus before their burning eyes. The forces struck, visibly and invisibly, and the smoke-black Graz’zt seemed to shake and thin and nearly disappeared under the withering power sent against it. Well it should, for enough force to destroy a small mountain had been expended. ‘Again!' screeched both of the demon king’s baboonlike heads. ‘Finish him!’"
