Japanese Water Torture
Japanese Water Torture is a combination of Worm and the Hammer programs. It spends time testing the target data wall with low-power probes to find its weak points. The longer you let it run, the more certain its ability to deconstruct the wall. It takes a minimum of 2 turns to work; each additional turn spent allowing it to probe adds +1 to its Strength (maximum Strength 7). Of course, the 'runner is usually hanging around outside the wall, waiting for this to work—a dangerous proposition. Some 'runners think that this program is named for the torture it inflicts on the user, not the wall! A data wall that has an active defense (see page 67) get a detection roll (Wall ICE Strength + 1D10 vs. Water Torture invisibility rating 5 + 1D10) to detect whether it's currently under attack, and react accordingly.
Options: Endurance, Invisibility
