Relentless Will

Your spirit is indomitable, and even against all odds you find yourself unable to give in to the forces that oppose you.

Make a Wisdom Saving Throw (DC 10) whenever you take damage that would reduce your hit points to 0.

If you succeed be reduced to 1 hit point instead. If you fail, you become unconscious. However, you may decide to not go prone as you force your body to keep standing defiantly even when unable to continue fighting through the sheer force of your subconscious will.

Every time you succeed mark a retroactive exhaustion point that will only take effect at the end of combat.
