Devour

Holding a smallish object in your hand and muttering the trigger phrase "Butter up the booty" causes the object to be turned into a soup can full of raw arcane energy. You pop open the can to consume the "arcane soup" and roll an effect on the Wild Magic Surge table using a percentile die, rerolling on a 1, 2, 99, or 100. Other cosmetics and effects are determined by your DM.

Feel free to have fun with this one, it's more freeform. DMs, don't be afraid to change the effects or make up your own separate tables like I did!
