Wall of Bone

You cause a vertical bone wall, anchored to the floor, springs into existence at a point you choose within range. The wall of bone is 6 inches thick and is composed of ten 10-foot-by-10-foot panels. Each panel must be contiguous with at least one other panel. Alternatively, you can create 10-foot-by-20-foot panels that are only 3 inches thick.

If the wall cuts through a creature’s space when it appears, the creature is pushed to one side of the wall (your choice). If a creature would be surrounded on all sides by the wall (or the wall and another solid surface), that creature can make a Dexterity saving throw. On a success, it can use its reaction to move up to its speed so that is no longer enclosed by the wall.

The wall is an object made of bones that can be damaged and thus breached. Each panel has AC 10 and 10 hit points per inch of thickness and has vulnerability to bludgeoning. Reducing a panel to 0 hit points destroys it. A destroyed panel doesn't remove the rest of the wall.

One side of the wall, selected by you when you cast this spell, is flat and featureless polished bone, whilst the other manifests bony arms that attack anyone attempted to approach. When a creature ends its turn within 5 feet of that side you can make a melee spell attack against the creature. On a hit, the creature takes 1d6 bludgeoning damage.
