Raise a wall of non-magical, solid stone.

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 Fortitude.

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 Vitality per inch of thickness. Reducing a panel to 0 Vitalitys destroys it and might cause connected panels to collapse at the GMD.

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.

Your fingers trace invisible lines, and the ground trembles in response. A wall of solid stone bursts forth, each panel interlocking into an imposing barrier, towering and unyielding. The air hums with the weight of its permanence.
