The Elder Scrolls: Tamriel

You create a bolt of lightning that arcs toward a target of your choice within range. Three bolts then leap from that target to as many as three other targets, each of which must be within 30 feet of the first target. A target can be a creature or an object and must make a Dexterity saving throw. The target takes 10d8 lightning damage on a failed save, or half as much on a successful one. Each of the secondary targets must also make a Dexterity saving throw, taking the same amount of damage.
