Baffling Smite

The next time you hit a creature with a melee weapon attack during the spell's duration, your weapon wounds the creature's mind as well as its body. The attack deals an additional 2d6 psychic damage and the target must succeed on a Wisdom saving throw, or be affected. On a successful save, the spell ends.

While the spell lasts, the affected target cannot take reactions and must roll a d6 at the start of each of its turns to determine its behavior for that turn.

d6 Behavior

1 The creature uses all its movement to move in a random direction and doesn't take actions.

2-4 The creature doesn't move or take actions

5-6 The creature can act and move normally.
