Acidic Dart

An orange blob of corrosive acid streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, it takes 1d8 acid damage, and if the creature is wearing armor its armor class is reduced by 1 until the start of your next turn.

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