Wall of Bones

A wall of animated bone springs into existence at a point on the ground that you can see within range. You can make the wall up to 40ft long,  but it is always 10ft high and 5ft thick. Each creature within the walls space when it appears are pushed to a side of your choice. Creatures that start or end their turn within 5ft of the wall take 1d6 slashing damage from waving weapons. The wall lightly obscures vision but is an object and can thus be breached. Each 5ft by 10ft high section of the wall has AC 10, 30 hit points, and immunity to poison and psychic damage. When a section of the wall is reduced to 0 hit points it is destroyed and crumbles away.

At higher levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
