Blood to Acid

You attempt to raise the acidity in a target's blood. Target a single creature within range; they must make a Constitution saving throw. On a failed save, the target takes 6d12 Acid damage, drops prone, and falls unconscious. It can make another save at the start of each of it's turns to attempt to regain consciousness. On a successful save, the target takes half damage, does not drop prone and does not fall unconscious.
