You are used to exceeding your limits, you can deny the exhaustion of doing a demanding activity with your great mental and psychic stamina.
- Whenever you complete a short rest, your exhaustion level, if any, drops by 1.
- Also if you are being conditioned by 1 or more levels of exhaustion, you can use an action to ignore them all for 6 hours. you can continue to receive levels of exhaustion, but these will have no effect. You can only use this feature 1 time per long rest. If you reach exhaustion level 6 during this 6 hours, you do not die, instead, you will pass out at 1 hp when the effect ends and will not wake up until you have completed a long rest.
