When the spell is cast, you are able to remove the evil force that corrupts a small/medium sized creature with an evil alignment or any small/medium evil entity within 20 ft. The black, chaotic ball of energy that emerges from the target can be redirected at another target within range and deal 1d6 necrotic damage. The target must make a successful Constitution Saving Throw to be spared the spiritual extraction. When the turn is over and the creature is 'exorcised' (or free of its corrupt spirit), the target must surrender its weapons (if any) and depart from the encounter in peace. The target is also no longer considered a threat or foe.
The spell counts as one action and once the spell is cast, the turn is over.
