A nonmagical wall of earth springs into existence at a point you choose within range. The wall is 6 inches thick and is composed of a single 10-foot-by-10-foot panel.   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 earth. You can crudely shape the wall to create crenellations, battlements, and so on.   The wall is an object made of earth that can be damaged and thus breached. The wall has AC 13 and 15 hit points. Reducing the wall to 0 hit points destroys it.   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.
