A wall of force spell creates an invisible barrier in the locale desired by the caster, up to the spell’s range. The wall of force will not move and is totally unaffected by any other spells, including dispel magic, save a disintegrate spell, which will immediately destroy it. Likewise, the wall of force is not affected by blows, missiles, cold, heat, electricity, or any similar things. Spells or breath weapons will not pass through it in either direction. The magic- user can, if desired, shape the wall to a hemispherical or spherical shape with an area equal to his or her ability, maximum of 20 square feet per level of experience. The material component for this spell is a pinch of powdered diamond.
