Wall of Bones

A nonmagical wall of bones springs into existence at a point you choose within range. The wall 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. Though solid, the wall has many small openings and gaps, and provides three-quarters cover to attacks from the other side. The wall is an object made of bones that can be damaged and thus breached. Each panel has AC 15 and 15 hit points per inch of thickness. Reducing a panel to 0 hit points destroys it and might cause connected panels to collapse at the DM’s discretion. When the wall appears, each creature within its area must make a Dexterity saving throw. On a failed save, a creature takes 4d8 piercing damage, or half as much damage on a successful save. creature can move through the wall, albeit slowly and painfully. For every one foot a creature moves through the wall, it must spend 4 feet of movement. Furthermore, the first time a creature enters the wall on a turn or ends its turn there, the creature must make a Dexterity saving throw. It takes 4d8 slashing damage on a failed save, or half as much damage on a successful one.

When you cast this spell at 7th level or higher and you maintain your concentration on this spell for its whole duration, the wall becomes permanent and can’t be dispelled. Otherwise, the wall disappears when the spell ends.

At Higher Levels When you cast this spell using a spell slot of 5th level or higher, both types of damage increases by 1d8 for each spell slot above.
