You send your mind and soul into the target's body, attempting to take control. The target must attempt a Will save. If you want to exert less control over the target, you can choose to use the effects of any degree of success more favorable to the target.
While you're possessing a target, your own body is
unconscious and can't wake up normally. You can sense everything the possessed target does. You can
Dismiss this spell. If the possessed body dies, the spell ends and you must succeed at a Fortitude save against your spell DC or be
paralyzed for 1 hour, or 24 hours on a critical failure. If the spell ends during an encounter, you act just before the possessed creature's initiative.
Critical SuccessThe target is unaffected.
SuccessYou possess the target but can't control it. You ride along in the body while the spell lasts.
FailureYou possess the target and take partial control of it. You no longer have a separate turn; instead, you might control the target. At the start of each of the target's turns, it attempts another Will save. If it fails, it's controlled by you on that turn; if it succeeds, it chooses its own actions; and if it critically succeeds, it forces you out and the spell ends.
Critical FailureYou possess the target fully, and it can only watch as you manipulate it like a puppet. The target is controlled by you.
