Crimson Fuel

Bonus Action. As a bonus action, you can sacrifice 1d6 hit points for every two cleric levels you have (round down). Choose one of the following effects:

• Empower an Ally. One creature you can see within 30 feet gains a bonus to its next attack roll, saving throw, or ability check equal to your Wisdom modifier, and it deals extra damage equal to your proficiency bonus on its next successful weapon or spell attack before the start of your next turn.

• Empower Yourself. You gain the same benefits as above (the bonus and extra damage).

The damage you take from this feature ignores temporary hit points.

You can use Crimson Fuel a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.
