A Wall of Force spell creates an invisible barrier in the locale desired by the case, up to the spell's range. The wall of force cannot move and is totally unaffected by most spells, including dispel magic. However, a disintegrate spell will immediately destroy it, as will a rod of cancellation or a sphere of annihilation. Likewise, the wall of force is not affected by blow, missiles, cold, heat, electricity, etc. Spells and breath weapons cannot pass through it in either direction, although dimension door, teleport, and similar effects can bypass the barrier.
The wizard can, if desired, form the wall into a spherical shape with a radius of up to 4 feet plus 1 foot per rank over 10th, or an open hemispherical shape with a radius of 5 plus 2 feet per rank over 10th. With this configuration, teleport, dimension door or other similar effects cannot penetrate the sphere in either direction. Otherwise, the wall is a flat surface of 50 square feet per rank, with a minimum dimension of 5 feet (i.e., at rank 1, it can be 5 feet by 10 feet but not 2 feet by 25 feet or 1 foot by 50 feet). The spell must be anchored to a solid surface, usually the ground. It can be used to form a bridge, as long as at least one end is anchored to the ground.
The wall of force must be continuous and unbroken when formed; if its surface is broken by any object or creature, the spell fails. The caster can end the spell on command. |
