Enrage

3rd-level enchantment

Casting Time: 1 action
Range: 120 feet (20-foot-radius sphere)
Components: V, S, M (a red handkerchief)
Duration: Concentration, up to 1 minute
Class: Bard, Sorcerer, Warlock

You attempt to create violent emotions in a group of people. Each humanoid in a 20-foot-radius sphere centred on a point you choose within range must make a Charisma saving throw; a creature can choose to fail this saving throw if it wishes. A creature that fails this saving throw becomes enraged for the duration.

While enraged, a target becomes hostile towards all creatures. An enraged creature that is concentrating on a spell must succeed on a DC 10 Constitution saving throw at the start of each of its turns or lose concentration on the spell.

As an action, you can force an enraged creature to use its reaction to make one melee weapon attack against one randomly determined creature within the enraged creature’s reach. If the enraged creature was friendly towards the target of its attack before this spell was cast, the enraged creature can repeat the saving throw immediately after making the attack, ending the effect on itself on a success.

An enraged creature can repeat the saving throw whenever it takes damage, ending the effect on itself on a success. When the spell ends, the creature re verts to its previous disposition again, unless the GM rules otherwise.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher and use an action to force an enraged creature to make a melee weapon attack, you can force one additional enraged creature to make a melee weapon attack for each slot level above 3rd.
