Ul's Arrow

A streak of blue ice flies at your targets! Make a ranged spell attack against the target. On a hit, the target takes 5d12 acid damage immediately and 1d2 acid damage at the end of its next turn. On a miss, the arrow splashes the target with acid for half as much of the initial damage and no damage at the end of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 8th Level or higher, the damage (both initial and later) increases by 1d12 for each slot level above 7th.
