Ebonflame Bolt

You hurl a mote of black fire at a creature or object within range. Make a ranged spell attack against the target, add a 1d4 to the attack roll, and subtract that same roll result from your health. On a hit, the target takes 1d10 fire damage. The ebonflame extinguishes immediately after impact, dispersing into shadow.

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