You unleash subtly enchanted words of encouragement and insult, escalating combat between two creatures within range who can hear you. Until the spell ends, you may deal 1d6 psychic damage to a target whenever the other one hits it with an attack. Also, one of the targets must succeed on a Wisdom saving throw, or attack rolls the other one makes against it have advantage (you choose who makes the saving throw).

If one target drops to 0 hit points before this spell ends, you can use your reaction to target a new creature.
