Exorcise

You shout holy words of power at a creature you can see within range. The creature must make a Charisma saving throw:

Failure: The creature takes 1d6 radiant damage, if the creature is undead it has Disadvantage on attack rolls against you until the end of your next turn.
Success: The creature is unaffected.

This spell can directly target a creature possessing another creature's body, even if the possession would normally make it untargetable.

Cantrip Upgrade. The damage increases by 1d6 when you reach levels 5 (2d6), 11 (3d6), and 17 (4d6).
