Luminous Stardust Healing

You scatter twinkling sparks from your sentinel weapon, replenishing your allies' fighting spirit and driving out evil. The target regains 16 Hit Points. If they were affected by a possession effect, you attempt to counteract the effect, casting out the possessing entity on a success and preventing them from possessing the target again for 1 week. If you fail, the entity is immune to being cast out by this spell for 1 week, though you can still heal the target as normal.
