wayfinder’s guide states Warforged don’t get exhaustion from lack of rest. Does this refer to long travels or not “sleeping” enough? Can they get exhaustion from other stuff like barbarian frenzy? Warforged Resilience is intentionally specific: you don’t gain exhaustion *due to lack of rest*. You aren’t immune to exhaustion from other sources, including berserker rage. Warforged don’t need to rest unless they want the benefits of resting: healing, spell restoration, etc.
