Mirror Strike

1st-level transmutation

Casting Time: 1 action

Range: Self

Components: V, S, M (a shard of mirror)

Duration: 1 round

Classes: bard, sorcerer, warlock, wizard

You momentarily alter the flow of time to split an attack, which you must make before the end of your next turn.

On your next melee attack, compare the result of your attack roll to the AC of two targets you can reach. If either opponent has advantage on their attack roll against you before the end of the mirror strike, you also gain advantage on your attack roll against that target. If your attack roll hits both targets, you deal half damage to each target. If it only would hit one target, you deal full damage to that target.

Damage from a critical hit is applied just like damage from a normal hit would be. If you miss both targets, or if you do not make a melee attack before the spell ends, the effect is wasted.
