This skill would be used to try and pick locks that you do not have a key for. I could see four levels of this and each level gives you the ability to get the lock open on the first try.
this would take a long time to get but would be useful for the ones that can not find keys
so at level 1 you have a 10% chance and a 20min cool down
level 2 20% Chance and 10 min cool down
etc..
