Confusion

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.

d10	Behavior
1	The creature uses all its movement to move in a random direction. To determine the direction, roll a d8 and assign a direction to each die face. The creature doesn't take an action this turn.
2-6	The creature doesn't move or take actions this turn.
7-8	The creature uses its action to make a melee attack against a randomly determined creature within its reach. If there is no creature within its reach, the creature does nothing this turn.
9-10	The creature can act and move normally.

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.
