You understand that your goal is more important than your survival, like the guardian Solwatch of old, and have gained the ability to channel all of your conviction into a desperate attack. Whenever you make a weapon attack roll, you can reduce your hit points by three-fourths. If you do, the attack deals an additional number of d10s of radiant damage equal to your proficiency bonus if it hits. Whenever you do this, you also gain a level of exhaustion.
