Barbarian in a can

Drinking the potion will swap your class to Barbarian for the next (d20) rounds of combat or until you get into combat. Points, Weapons, and other items from your previous class will carry over, and cannot be removed while you are in 'Barbarian Mode'. Takes 1 bonus action to be drank, and can be used 3 times, then thrown as a ranged 'weapon', which will deal 1d4 damage upon impact with the can. Can probably be found in black markets or second-hand stores.
