Lockpicking

In order to attempt to open a target chest you must first acquire some Lockpicks. Use these on the target lock and you will attempt to break it. Depending on the complexity involved versuses your current skill you have a chance of breaking the pick altogether should you fail, so a well prepared rogue brings plenty of extras. Note that often after disabling a lock, you may still have to deal with a few Chest Traps.
