Darkflame

You shoot a pitch-black ball of fire. Make a ranged spell attack against the target. On a hit, the target takes 1d8 necrotic damage. Additionally, the target has disadvantage on the next damage roll it makes. Plants are vulnerable to this spell's damage, and anything that hits 0 hit points because of this spell becomes a shriveled husk of what it once was.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
