@JeremyECrawford Could a barbarian hurt himself to maintain rage? How would you rule it? If so, could he then control the dmg dealt on himself?

The Rage feature refers to the barbarian taking damage. The feature doesn't care how you take the damage: from someone else or yourself #DnD https://t.co/nGlxMusgxS
