  A shimmering green arrow streaks toward a target within range and bursts in a spray of acid.  Make a ranged spell attack against the target.  On a hit, the target takes 4d4 acid damage immediately and 2d4 acid damage at the end of its next turn.  On a miss, the arrow splashes the target with acid for half damage and no damage at the end of its next turn.
