Void Wall

Recharge 33%, std, ranged, wall 1/level, concentration; you create a wall of darkness that causes part of the matter and energy passing through it to disperse into the Void. It isn't a wall-shaped portal — that would be devastating — but rather a two-dimensional area where quantum particles lose their alignment with the Prime Material, causing them to disperse into the larger interdimensional space surrounding the Universe. The majority of particles quantum tunnel past this wall, so only a fraction are affected.

All creatures and objects suffer heavy disintegration damage when crossing the wall; Dex half, with success causing the creature to stay on their original side, not crossing but merely brushing the wall.
