Description
4th-level enchantment


 * Casting Time: 1 action
 * Range: 90 feet
 * Components: V, S, M (three nut shells)
 * Duration: Concentration, up to 1 minute

This spell assaults and twists creatures' minds, spawning delusions and provoking uncontrolled action. Each creature in a 10-foot-radius sphere centered on a point you choose within range must succeed on a Wisdom saving throw when you cast this spell or be affected by it.

An affected target can't take reactions and must roll a d10 at the start of each of its turns to determine its behavior for that turn.

At the end of each of its turns, an affected target can make a Wisdom saving throw. If it succeeds, this effect ends for that target.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the radius of the sphere increases by 5 feet for each slot level above 4th.
