Crippling Claws of Lightning

Choose a humanoid that you can see within range. The target must succeed on a Wisdom saving throw or be paralyzed for the duration. At the end of each of its turns, the target can make another Wisdom saving throw. The creature is restrained by claw-like arcing conduits of arcane electricity, and whenever a creature rolls a saving throw for this spell, this spell deals 1d4 lightning damage to that creature for each creature targeted by the spell and also currently paralyzed this way. On a success, the spell ends on the target. For example, if Crippling Claw is cast targeting two creatures, both take 2d4 lightning damage each time this spell forces the roll of a saving throw until one creature can end the paralysis effect on themselves, reducing this spell's damage to 1d4 at that time.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can target one additional humanoid for each slot level above 3rd. The humanoids must be within 50 feet of each other when you target them.
