Berserk

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

On a failure the creature(s) loses all sense of self and flies into a blind rage. During this rage the creature(s) must spend any movement and action trying to melee attack the nearest closest target with what ever they were holding when they were first affected by the spell. If there is more than one combatant next to the creature the DM determines who is attacked.

At the end of each of its turns, an affected target can make a Charisma 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.
