This was unexpected. In order to sneak into the castle, Edgin has Simon the wizard duplicate him as an illusion, strolling up to the guards and singing a jaunty tune. Unfortunately, the spell starts to go awry, Faux-Edgin’s voice starts skipping like a record, and then… he starts physically warping, like Photoshop has gone horribly wrong. His eyes get huge, his mouth extends horribly, and his head starts sinking into his torso. It’s horrific and horrifically funny, and we’d be surprised if DMs didn’t start making their players’ illusion spells fail in the exact same way.
