Bag of Many Candies

A small leather pouch that has 21 (or 3d10) pieces of multicolored candies. Each candy is relatively spherical, some may have small imperfections or lumps on them. Each piece can be either sweet or sour. Eating a piece of candy results in one of the following effects happening to the character (roll 1d20), or one of the DM's choosing. Melting or dissolving the candies results in no effects. All effects are either instant, or last 15 minutes. It takes a Bonus Action to consume a piece. Consuming a second piece ends the effect of the first piece.
