Wall of Stone

Unlike wall of iron, wall of stone proves useful to the typical stronghold builder, and the costs for hewn stone walls in Chapter 2 assume you use this spell when it’s more efficient than traditional stonecarving. The spell allows you to crudely shape the wall however you like, so you can build corners, doorways, and whatever architectural features you like. Only crude control is available, and you must still hire stonecarvers or use stone shape if you want fine detail.

The typical casting (by a 9th-level caster) gives you a 225-square-foot wall, 2 inches thick. Alternatively, you can halve the thickness (to 1 inch) and double the area (to 450 square feet). The DC for a Strength check to break it is either 22 (for a 1-inch-thick wall) or 24 (for a 2-inch-thick wall).

Despite the name, you can use wall of stone to build almost anything—a bridge, a throne, whatever you can come up with as long as it merges with and is supported solidly by existing stone. If the wall of stone is made to go over a span of more than 20 feet, it must be buttressed, cutting its overall area in half.

Casting: 450 gp (Clr9 or Wiz9) or 500 gp (Sor10) or 660 go (Drd11)
