You designate a humanoid creature you can see within the range of the spell, and force the creature to make a Wisdom save. If the save fails, the creature will be charmed by you for the duration of the spell. A creature charmed in this way will have a twisted crown of iron jagged on top of its head, and its eyes will flash crazily.

Classes: Warlock, Sorcerer, Bard, Wizard
Casting Time: 1 Action
Range: 120 feet
Components: V, S

The enchanted target must launch a melee attack against a creature you specify in your heart before moving. If you do not specify a target for it, or if there is no target within its reach, the creature can act in its normal state during this turn.
After casting the spell, you must use your actions to maintain control of the target during each turn, otherwise the spell will terminate prematurely. In addition, the subject of the spell can also make another Wisdom saving throw at the end of each one’s turn. If the saving is successful, the spell ends.
