Chain Spark

You conjure a miniature storm cloud, which electrocutes a creature within range. You don't have to see the target if you know where it is. A target must succeed on a Dexterity saving throw or take 1d4 lightning damage. If you roll a 4 on the die, the electricity surges and leaps to another creature within 10 feet of the first target. The new target must make a Dexterity saving throw, as though targeted by the spell, which could cause the electricity to leap again.

A creature can be targeted only once by each casting of this spell.

This spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4). Starting at 11th level, you must roll a 4 on two of the dice for the electricity to leap.
