Discord

A haunting black orb hovers over the target creature that only you and other chosen creatures can see. The target receives an extra 1d4 force damage whenever it suffers an attack. A creature targeted by this spell has advantage against being charmed and disadvantage against being frightened. During the duration of this spell, the caster may switch targets as a bonus action or a reaction to taking damage from another creature within 15 feet of the original target.
