class WallOfStone(Spell):
    """A nonmagical wall of solid stone 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. 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. 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. Thus, you can use
    this spell to bridge a chasm or create a ramp. If you create a
    span greater than 20 feet in length, you must halve the size of
    each panel to create supports. You can crudely shape the wall to
    create crenellations, battlements, and so on. The wall is an
    object made of stone that can be damaged and thus breached. Each
    panel has AC 15 and 30 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. 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.

    masses (such as walls or trees) or layered across a floor, wall,

    in the webs or that enters them during its turn must make a
    Dexterity saving throw. On a failed save, the creature is

    a Strength check against your spell save DC. If it succeeds, it is
