Wall of Stone

Using this spell the caster creates a stone wall. The wall is composed of up to one 10'x10' square section, one foot thick, per caster level. The caster can form this wall into almost any shape, with some restrictions. The caster can increase the thickness of the wall with a proportionate reduction in the area; for example, doubling the thickness halves the area. The wall cannot be created such that it occupies the space of any object or creature. It must be adequately supported by existing stone, which it will bond with automatically, but need not be supported over its entire area. For example, a wall of stone may be formed into a bridge over a stream or chasm, so long as both ends of the bridge rest solidly upon (and bond with) existing stone. Bridges longer than 20 feet must be arched, buttressed, or both in order to stand; this extra construction reduces the wall's usable volume by half, as does creating a wall with battlements, crenelations, and similar basic structural elements. No complex structural elements may be created by this spell. Though made by magic, the wall is made of stone and can be broken or damaged just as if it were ordinary stone. The wall can be formed into a container to trap creatures, and if this is attempted the targets of the spell are allowed to save vs. Death Ray to avoid being trapped. If the save is successful the targets are able to make up to one full move to a space outside the container.
