Deicide's Judgement

You siphon the magical or divine momentum of an enemy to punish them. The creature must make a Constitution saving throw. On a failed save, the spell or legendary action fails and is wasted. Furthermore, the target takes 1d10 Force damage per level of the spell they attempted to cast (minimum of 1d10 for cantrips or legendary actions). You then absorb a portion of this disrupted energy; your next weapon or spell attack roll before the end of your next turn deals an extra 3d6 Force damage.
