You create a bolt of lightning that arcs toward a target of your choice that you can see within range. Bolts then leap from that target to another target for up to three additional targets. The new target must be within 30 feet at least one other target of the spell. Any target can be targeted by only one of these bolts per casting of this spell.

Each target must make a Dexterity saving throw. A target takes 8d12 lightning damage on a failed save and it can’t take reactions until the end of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, two additional bolts leaps from the first target to other targets for each slot level above 6th. When you cast this spell using a spell slot of 9th level, you instead have the bolt leap to as many targets as you designate.
