Voltaic Arc

You crack an arc of lightning at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 lightning damage. If you don't have line of sight, you may instead target a metallic surface that has line of sight with the creature to successfully ricochet the lightning damage to the target.

Cantrip Upgrade. This spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
