Arc Flash

You snap your fingers, releasing a chain of minor electrical arcs that jump between multiple enemies. Choose one creature within range. It takes 1d6 lightning damage and, if another creature is within 10 feet, a second bolt arcs to them, dealing half the damage of the first hit.

This process continues, reducing the damage by half each time, until it hits a maximum of 3 creatures or reaches 1 damage.

At Higher Levels (Character Level): The initial damage increases to 2d6 at 5th level, 3d6 at 11th level, and 4d6 at 17th level.
