A creature of your choice that you can see within range suddenly is overwhelmed by incapacitating pain, if this spell affects it. The target must succeed on a Wisdom saving throw or fall prone and becomes incapacitated for the duration. A creature with an Intelligence score of 4 or less isn’t affected. The most common phantasmal pain in humanoids is a blinding white back pain where movement makes the pain even worse.

If the creature takes a movement action while affected (e.g., crawling or standing) the target takes 2d8 psychic damage.

At the end of each of its turns, the target creature makes another Wisdom saving throw. On a failure, they are left incapacitated and fall prone. On a success, the spell ends and the manifested pain completely fades.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage when the creature moves increases by 1d8 for each slot level above 3rd.
