Wall of Scales

A magical wall of snake scales springs into existence at a point you choose within range. The wall is 5 feet 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 5 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 it is no longer enclosed by the wall or structure.
The wall can have any shape you desire, though it can’t occupy the same space as a creature or object. The wall doesn’t need to be vertical or rest on any firm foundation. It must, however, merge with and be solidly supported by existing stone or an altar to your deity using one of the panels. Thus, you can use this spell to bridge a chasm, create a ramp, create a home, create a structure, or build sculptures.
If you create a span greater than 20 feet in length, you must use at least 2 panels to create supports. You can creatively shape the scales to create crenelations, battlements, and so on.
The wall is an object made of snake scales that can be damaged and thus breached. Each panel has AC 16 and 90 hit points. Reducing a panel to 0 hit points destroys it and might cause connected panels to collapse at the GM’s discretion.

Each panel, is resistant to the following damage types: acid, poison, fire, cold, lightning, thunder, and slashing damage. In addition the walls can be repaired by splashing fresh humanoid blood upon a damaged area, or by casting mending. Fresh blood heals 30 hit points, and mending heals in 5 hit points per cast.
If 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
