Agony Star

You create two glowing mote on the tips of your fingertips, middle, and thumb creating an electric arc between them.  On a successful grapple the target takes 3d8+3 electric damage and is stunned until the grapple is broken via successful strength save (DC 25) this damage will continue each turn so long as the grapple continues. The target is allowed to attempt a save on each of their turns.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the spell creates one more mote and damage die for each slot level above 3rd with a maximum of 5. Example, if cast using a 4th level slot there would be three motes, 4 at 5th and 5 at 6th.
