GH 24: Fiend 3 — Gift of Second Chances

This is a Gift of Damnation you can receive from the Devilish Contractor Boon.

When you are reduced to 0 Hit Points, you can use your Reaction to roll a Hit Point Dice. If you roll a 2 or better, set your Hit Point total to the result of the roll. If not, you suffer a Death Saving Throw failure. You regain the use of this gift when you finish a Long Rest.
