Effects
This spell creates a wall of granite rock that merges into adjoining rock surfaces. It is typically employed to close passages, portals, and breaches against opponents. The wall of stone is 0.25 inch thick and up to 20 square feet per level of experience of the wizard casting the spell. Thus, a 12th-level wizard can create a wall of stone 3 inches thick and up to 240 square feet in surface area (a 12-foot-wide and 20-foot-high wall, for example, to completely close a 10-foot x 16-foot passage). The wall created need not be vertical, nor rest upon any firm foundation (see the wall of iron spell however, it must merge with and be solidly supported by existing stone. It can be used to bridge a chasm, for instance, or as a ramp. For this use, if the span is more than 20 feet, the wall must be arched and buttressed. This requirement reduces the area of effect by half. Thus, a 20th-level caster can create a span with a surface area of 200 square feet. The wall can be crudely shaped to allow crenelations, battlements, and so forth by likewise reducing the area. The stone is permanent unless destroyed by a dispel magic or disintegrate spell, or by normal means such as breaking or chipping.
