The gods demand that you undergo trials to curry their favor, granting you the following benefits.
Sacrificial Strike
When you deal damage to a creature with a Melee weapon or Unarmed Strike, you can take a Bonus Action to enhance the strike. You take 5 Radiant damage and the target takes an extra 10 Radiant damage. This damage ignores your Resistance and Immunity, and bypasses your Temporary Hit Points.
Sacrificial Skill
Once per turn when you fail a D20 Test, you can take 10 Radiant damage to gain a +5 bonus to that roll, potentially turning it into a success. This damage ignores your Resistance and Immunity, and bypasses your Temporary Hit Points. If the test still fails, you don't take this Radiant damage.
