@PhoenixNorg @Clint_CranfordBut Rage continues if he takes damage? That’s correct.

@JeremyECrawford @Clint_Cranford Then a barbarian COULD indeed hurt themselves to keep rage going. So “yes” to the original question?

Barbarians can’t keep Rage going by simply attacking themselves (must be a hostile creature), but they can deal damage to themselves. #DnD https://t.co/jRUDHTBl4O
