Deny Death

Level 18

You are immune to death effects and negative levels. If you
would normally die from damage, as long as you have at least 1 Resolve Point remaining, you can immediately spend all of your remaining Resolve Points to instead stay alive. If your Hit Points would have been reduced to 0, you now have 1 Hit Point instead. Once you use this ability, you can’t regain Resolve Points again until you rest for 8 hours, even if you have another means to do so.
