Arcing Bonds

Lightning arcs from you to up to three creatures of your choice that you can see within range, creating separate bonds between you and each target. A target breaks its bond if it is ever more than 10 feet away from you, or when the spell ends. If a target is still bonded to you at the start of its turn, it must make a Constitution saving throw. The creature takes 3d8 lightning damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2rd
