At 4th level, a cleaner is able to study a location, conceal evidence, and hide in or extricate himself quickly from that location. Studying a location takes 1 minute for each 10-foot square. Once he has studied an area, the cleaner can attempt a Disguise check to alter evidence or a Stealth check to conceal evidence (by cleaning up bloodstains, obscuring footprints, moving a dead body, and so on). Altering a location takes 1d3 × 10 minutes of work per 10-foot square. Anyone attempting to determine what actually happened in that area must succeed at an opposed Perception check against the result of the cleaner's Disguise or Stealth check (cleaner's choice) or accept the altered scene as truth. The cleaner gains a +4 bonus on this check, on Sleight of Hand checks to hide objects from that location on his person, and on Stealth checks to hide within or escape from that location. The benefits of this ability last as long as the location remains unaltered (except by the cleaner). This ability replaces the slayer talent gained at 4th level.
