[QUOTE="Norfleet, post: 1169923, member: 11581"] Hardness is a property of how much is required to scratch, bend, warp, or otherwise mar it. A wall of force therefore has infinite hardness, since it's indestructible and nothing can scratch, chip, or otherwise damage it. Sharpness isn't really a property of the wall of force itself, but is simply how thin the edge of an object is: A wall of force is a 2-dimensional object, and as such, having no width, possesses infinite sharpness. I would think it would be hard to hang on a wall of force, since Walls of Force are vertical. Let's say for the sake of argument that some force, perhaps decompression, provides you with a force that causes you to fall in a nonvertical direction. If you simply hang from the edge of that wall of force, nothing inherently happens to your fingers, until they happen to slide inwards on the plane. The wall of force is, of course, impenetrable, and 2-dimensional, so your fingers slide downwards without penetrating, since the wall has no third dimension of thickness to stop your fingers from doing this. Unfortunately, the effect is that the grasping part of your fingers now happens to be on the opposite side of the wall of force from the rest of you. Walls of Force are impenetrable to other forces and objects, such as your fingers' attempt to stop you from being pulled off by the other force which necessitated the clinging. Therefore, you fall under the influence of that other force....but walls of force are impenetrable. Your fingers, on the opposite side of the wall, cannot be pulled along with you, because that would necessitate it passing through the wall of force. So they stay there, and your fingers are thus cut off. It's immovable. It's impenetrable, which means it's infinitely strong, because if it were not infinitely strong, then a finite force would be able to penetrate it, thereby meaning it's not impenetrable. It's infinitely hard, because it's completely immovable in all parts, and therefore perfectly rigid and cannot be bent, scratched, or chipped by anything. It's an immovable, impenetrable plane. Impenetrable planes, of course, happen to be the exact description of a perfect razor. Actually, in a collision where you just stop moving, what you have is the ideal inelastic collision with an immobile object of effectively infinite mass. Your kinetic energy can't be transferred to the object at all, and as a result, this kinetic energy becomes painfully converted into damage to you. It's very much like splatting into the Earth, only without the Earth moving a little bit. Still, the splatting has to be conserved somehow, and therefore becomes that much more damage to you. Unless you're suggesting that somebody falling onto a wall of force as a result of gravity alteration or being hurled incurs absolutely no damage. Alternative interpretations offered include that the wall of force dispels when this happens, because it is no longer unbroken....except that walls of force are impenetrable, and such a thing would violate the impenetrability. Yet, as planes, they're also two-dimensional, so offer no resistance to vertical motion into the edge. Of course, walls of force aren't rated as doing any damage, so this process of being bisected would be relatively harmless, causing no damage whatsoever, much as falling is harmless, and characters can fall forever while suffering no damage whatsoever. It's the sudden stop at the end which hurts. So the victim who was cut in half wouldn't suffer any kind of damage from the actual process of being cut in half: It doesn't cause any amount of slashing, piercing, bludgeoning, or force damage. However, being in two pieces is bad, and causes the creature to rapidly bleed to death as a result. Presumably, if the cut-in-half creature was a troll, he would be undamaged by this process of being cut in half, but he would still be cut in half and have to regenerate his missing half. Still, he'd have all of his hitpoints and the use of the greater half of his body and could seek the other half of his body to reattach with, during which the party could be attacked by either of the two half-trolls. So it's not a perfect end-all-be-all tactic either, particularly when faced with monsters undaunted or even strengthened by bisection, as any DM will surely start to make use of when faced with this. That, or possibly spell-resistant monsters who could crash through the wall of force with no effect whatsoever if they made their spell resistance, if SR applies to attempts to crash through walls of force. Next question: Walls of Force are invisible. Does this mean they would be visible under true seeing or see invisibility, or are they invisible by virtue of being devoid of any visible form, and therefore remain invisible? [/QUOTE]
