Wear upon your visage the mark of serene suffering, a testament to your belief and spirit. Let the last thing the guilty see be the stern face of the Bloody Mother.

Terrible Repose. Whenever you slay a creature with a CR above 0 while wearing this helm, you can spend a bonus action to absorb their essence into your being and regain a hit die.

Inflict Alleviation. As an action you can spend up to 3 hit dice to prolong the suffering of those around you. Roll the hit dice spent and divide a number of temporary hit points equal to the number rolled as you choose among any number of creatures you can see within 30 feet of you.

Once you use this property it can't be used again until the next dawn.

As the Mother has sent us, so shall we send her children into her arms to receive her terrible love. We shall be like a thunderous wave, never yielding against any opposition. Through her grace we shall bring forth nightmarish miracles.

-The Crimson Tome; Verse 50:11
