Effect P: Weaving an impassible barrier of magical energy, you instantly construct a wall made of force. The wall must be formed as a continuous, flat, vertical plane but the length and height of the wall are determined by you and must not exceed the maximum area(i.e. it can be 10 ft tall by 100 ft long or it can be 20 ft tall by 50 ft long). The wall cannot be moved and is immune to all forms of damage. It cannot be dispelled, but is subject to a Disintegrate Spell. Extra-dimensional transport (such as teleportation) can be effected through the barrier, but Ethereal creatures and travel is blocked. Abilities that require Line of Effect are blocked by the wall.
