You attempt to seize control of a target creature that you can see within range. The target must make a Wisdom saving throw. On a failed save, you possess the target’s body and control its actions. The target’s mind remains conscious but cannot control its body.
While possessing the target, you use your own Intelligence, Wisdom, and Charisma scores, but otherwise use the target’s statistics, gaining access to its knowledge, class features, and abilities. You cannot use your own class features, spells, or abilities, or those of the target that require a physical capability the target doesn’t possess. You also can’t access the target’s memories or knowledge beyond basic, surface thoughts.
The target can make a Wisdom saving throw at the end of each of its turns. On a success, the spell ends and you return to your body. If the target takes damage, it can immediately make another Wisdom saving throw to end the spell.
If your physical body takes damage while you are in control of the target, you must make a Constitution saving throw to maintain concentration. If you fail, the spell ends and you return to your body. If the spell ends, you cannot cast it again on the same target for 24 hours.
At Higher Levels: When you cast this spell using an 8th level spell slot, the duration is concentration, up to 10 minutes. When you use a 9th level spell slot, the duration is concentration, up to 1 hour.
