__TOC__
==Description==
In retaliation to being struck, you momentarily open a rift to the mirrored realm, causing a burst of reflective shards to materialize and lash out at your assailant. The attacker must make a Dexterity saving throw. On a failed save, the attacker takes 2d8 piercing damage and becomes "Mirrored" for 1 minute. 
While Mirrored, any attack the attacker makes will cause a duplicate of the attack to target a creature of your choice within range of the attacker, including possibly the attacker themselves. This duplicate attack uses the same attack roll and damage roll as the original. 
On a successful save, the attacker takes half damage and is not Mirrored.
