Monowire
Monowire (TL9^)
Deadly and nearly invisible, monowire can cut an intruder to pieces without warning. People who prefer less lethal defenses use fragwire or sensor wire, or mix an outer perimeter of ordinary wire with an inner perimeter of monowire.
Any roll to see monowire requires a Vision or Traps roll at -4 (-1 if a searcher is specifically looking for it). Anyone walking through a monowire "spiderweb" will take 2d(10) cutting damage per strand. This damage is reduced to 1d(10) if moving very slowly, and increased to 3d(10) if running. Care must be taken to avoid injury when stringing monowire, since it is hard to see and cuts almost anything. On a critical failure when using it, the user takes 1d(10) cutting damage to one hand.
