Self Mutilation

You've learned to transfer the pain you receive to your enemies. As a bonus action, you can choose to take a number of d10 necrotic damage to gain that many Mutilation Boons. Your Mutilation Boon lasts for 1 hour of until expended. There is no limit to the amount of Mutilation Boons you have.

You can expend this Mutilation Boon to gain one of the following benefits:

• When you make an attack roll, you roll 1d8 and add it to the total.
• When you hit with an attack or spell, you deal an additional 2d8 necrotic damage.
• When you cause a creature to make a Strength, Dexterity, or Constitution saving throw, roll a d4 and reduce their save by the amount rolled.

The damage you take to gain a blood boon can’t be reduced in any way.
