Components: V, S, M (a bit of fur, a piece of amber, glass, or a crystal rod, and three silver pins)
Duration: instantaneous
You create a bolt of lightning that arcs toward a target of your choice that you can see within range. Three bolts then leap from that target to as many as three other targets, each of which must be within 6 sqr. (9m) of the first target. A target can be a creature or an object and can be targeted by only one of the bolts.
A target must make a Dexterity saving throw. The target takes 10d8 lightning damage on a failed save, or half as much damage on a successful one.
