Barbarian Brew

This potion causes the drinker to be immediately be consumed in a savage, bloodthirsty rage that usually only true barbarians can enter. You rage for 1 minute, and while raging, gain advantage on STR checks and saving throws (not attacks), +2 melee damage with STR weapons, and resistance to bludgeoning, piercing, slashing damage. You can't cast or concentrate on spells while raging. Your rage ends early if you are knocked unconscious or if your turn ends and you haven’t attacked a hostile creature since your last turn or taken damage since then. Unlike a normal barbarian rage, you cant willingly end your rage early. This potion's yellow, gray, and green contents constantly boil and bubble.
