The Geometric Sphere is used primarily as a defensive combat function. Often it is used to capture enemies and contain them. The Sphere has a ¼// diameter per level. The sphere is gas permeable, and so does not cause asphyxiation. Moreover, it causes no damage to partially enclosed creatures (i.e. a 6' tall man enclosed by a 5' diameter sphere would undoubtedly be immobilized, but would otherwise take no damage.) An unwilling target gets a save versus area effect to avoid being enclosed. Large spheres can enclose more than one person or object. The sphere can be moved at the Mathematician's will at a rate equal to 1/2 the caster's base ground movement. Like most "Geometric" formulae, the Geometric Sphere has armour class of AC(5) with a +1 bonus to AC for every third level above level three, and has a single structural point.
