This spell creates an invisible barrier that will stretch no more than ten feet across. This spell must be cast with a freestanding anchors on either end with a straight line connecting the two, up to ten feet across and 25 feet high. The floor of the Wall of Force must be marked in some way (such as by a rope, chalk mark, or ribbon) to indicate to all observers that a Wall of Force is in place. Once the Wall of Force has been cast, the physical representation cannot be moved. Neither the Wall nor the frame may be Destroyed. The wall will last for ten minutes, but may be dropped by the caster at any time if he or she touches the phys rep and states “Wall down.” This statement is out-of-game, although any observers who hear the statement are aware that the wall was dropped, and they might know who dropped it. The Wall will also drop if hit by a Dispel. Multiple casters may cast the spell simultaneously to extend its width for 10’ per caster, much like Ward or Circle of Power can.
