Acme Anvil

You create a large anvil above one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d8 bludgeoning damage per 10ft the anvil falls. The anvil spawns up to 10ft above the target. Hit or miss, the anvil rings deafeningly. The target and each creature within 5 feet of it must succeed on a Wisdom saving throw or take 2d6 thunder damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the thunder damage increases by 1d6 and the spawn radius and drop hight increases at 10ft for each slot level above 2nd.
