Ivaldi's Impervious Anvil

4th-level evocation

Casting Time: 1 action
Range: 120 feet
Components: V, M (A tiny silver anvil worth at least 50 gp)
Duration: Concentration, up to 1 hour
Choose an unoccupied area on the ground within range that is 10 feet wide, 15 feet long, and 5 feet tall. A massive magical anvil that is translucent but tangible is summoned in the area. The anvil is a magical object that is unbreakable and immovable, allowing for objects to be worked on it with titanic force, such as that needed to work adamantine. The anvil can only be dismissed by a dispel magic spell of 6th-level or higher, antimagic, the wish spell, or if you stop concentrating on the spell. Incorporeal creatures that end their turn in the anvil’s space take double the damage they would normally take for doing so.
