Dissolving Droplets

You transmute mundane liquid into a corrosive acid, and hurl it at a foe to dissolve their defenses.

Make a ranged spell attack. On a hit, the target takes 1d4 acid damage, and their AC is reduced by 1d4 until the start of your next turn.

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