Does this trap have a lock mastery component in it? If so, which one?
>You carefully begin to examine a corroded steel strongbox for traps...
>After carefully examining the lock, you move on to the hinges of the strongbox. Just as you were to pass the strongbox off as safe, you notice what appears to be the ends of springs incorporated with the hinges. Seems rather odd to have a strongbox designed to spring open when it is unlocked.
>It looks like a rudimentary trap (-24).
>You still have a good enough picture of the trap in your mind, that you could try to disarm it.
