Corruption

Drawing on the ancient knowledge of a nagpa, the caster targets one creature it can see within 90 feet of it. The target must make a Charisma saving throw (DC 10 + caster's Charisma modifier). An evil creature makes the save with disadvantage. On a failed save, the target is charmed by the caster until the start of the caster’s next turn. On a successful save, the target becomes immune to the caster’s Corruption for the next 24 hours.

This spell can only be cast by those of Neutral or Evil alignments.
