Crackling Bolt

You hurl a mote of fire at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 fire damage. If the target is wearing armor made of metal it must make a CON save against your spell save DC or drop what it is carrying.

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