Use this skill to disarm a trap, jam a lock (in either the open or closed position), or rig a wagon wheel to fall off. You can examine a fairly simple or fairly small mechanical device and disable it. The effort requires at least a simple tool of the appropriate sort (a pick, pry bar, saw, file, etc.). Attempting a Disable Device check without a set of thieves’ tools (page 130) carries a -2 circumstance penalty, even if a simple tool is employed. The use of masterwork thieves’ tools enables you to make the check with a +2 circumstance bonus.
