Corrosive Sting

You launch an acid laced dart of bone at a target you can see within range. Make a ranged spell attack against the target. On a hit, the target takes 1d4 acid damage and takes 1d4 acid damage at the start of its next turn.

The spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
