Intergrated survival protocol

The perfect combination of steel, wood and engineering finesse allow warforged to survive unimaginable injuries. With multiple back up systems, an extremely damaged unit can activate it's redundant parts allowing it to continue it's designed task for as long as possible.

When a warforged would take damage that would reduce it's current hit points to 0 or less, survival protocol takes affect.

Instead of being knocked unconscious, the warforged instead is left with 1 hit point and immediately takes 1 point of exhaustion. It also becomes immune to fear for 1 minute.

This may activate once per long rest. A DC 12 intelligence check must be made before the next long rest to see if repairs can be sufficiently made. A failed check disallows survival protocol to take affect for 1 in game day length. After this time frame, the warforged will have had enough time to fully repair it self and survival protocol can once again activate.
