As two actions, a nonmagical wall of solid stone twice as big as normal springs into existence at a point within 20 meters that lasts for the duration. The wall can’t occupy the same space as a creature or object and doesn’t need to be vertical or rest on any firm foundation. It must, however, merge with and be solidly supported by existing stone.

If a creature would be surrounded on all sides by the wall (or the wall and another solid surface), that creature can make a Reflex 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 is an object made of stone that blocks line of sight. The wall can be damaged and thus breached. Each panel has 15 Defense, 3 Soak, and 2 Health per centimeter of thickness. Reducing a panel to 0 health destroys it and might cause connected panels to collapse at the GM’s discretion.

You can use this spell to bridge a chasm or create a ramp. If you create a span greater than 4 meters 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.

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.
