GH 24: Fiend 1 — Gift of Joyous Life

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

At the beginning of your turn, if you are Bloodied, you can choose to roll a Hit Point Die (no action required) and regain a number of Hit Points equal to the roll. If you roll a 1 on this die, you regain no Hit points and take 1 point of Force damage instead. You regain this ability when you finish a Short or Long Rest.
