Twin's Lament

In order to aid an ally within 30 feet, your shadow self physically manifests to assist your ally. You do so by harming the foe who hurt them but at a cost, you take [roll]2d6[/roll] force damage in an attempt to avenge your ally's damage and hit their foe with a force attack. The ally you cast this spell on gets +2 to their AC until the end of your next turn. This ability works on physical ranged/melee, and spell ranged/melee.

The attacker must succeed a Dexterity Saving Throw or take [roll]8d6[/roll] force damage, 1/2 damage on a successful save.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
