If you would die, or fall to 0hp you can activate this to make a last stand through your own willpower. After activating this ability you regain all hp, spell slots and any other physical trait ie ki or breath attack. However after you activate this ability for the next 24 hours anytime you drop to 0hp afterwards results in your immediate death. This ability does not regrow limbs or revert disintegration of body parts, however it does put out fire, cure you of any poison, shatters any ice freezing you and stops the bleeding of any wound and makes any fatal wound into non fatal wounds. If your body would be destroyed from an attack that kills you, you can make a constitution saving throw equal to the opponents save dc and you can resist the destruction but still feel the pain of the attack. This effect does not stack with other abilities that would prevent death or falling unconscious, if abilities like that have been used you can’t use this ability during the combat and vice versa. However effects that prevent death but don’t regain hp like stabilizing upon unconsciousness are still useable but once you use this ability they cannot save you. Any spell that prevents death has a 70% of not working after you activate this ability, and when someone casts a spell like that on you they are suddenly aware of this effect.
