Stigmata of Ashes

A halo-shaped burn scars your sternum, glowing faintly like dying embers. When you channel divine magic, gray smoke leaks from the wound. Holy and unholy energy war within your soul.

Whenever you use Divine Smite or cast a healing spell, you must succeed on a DC 13 Constitution saving throw or take 1d6 necrotic damage.

You have advantage on Intimidation checks against undead and fiends.

You have disadvantage on Persuasion checks against celestials, priests, or devout creatures.

Spells that detect creature type or alignment register you as both celestial and fiendish.

When within 1 mile of Malaphar, you take 1 damage per hour.

The Stigmata of Ashes can only be cleansed by one of the following acts: surviving Malaphar’s unholy smite in direct confrontation, completing a pilgrimage to the Abbey of Saint Markovia and bathing in its corrupted font, or sacrificing a divine relic of immense holiness (such as a Holy Avenger) burned to ash upon the wound. Failed attempts to purify the mark instead deepen its curse, permanently increasing its saving throw DC by 1.
