Acid Claw

Acid drips from your claws as you attempt to strike down upon a creature. Make a melee spell attack against the target. You have advantage on the attack roll if the target is unarmored. On a hit, the target takes 1d8 acid damage.

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