Thief Abilities (and Abilities for non-Thieves)
A Thief's skills and abilities are very dependent on their surroundings and circumstances; a list of modifiers follow. There are also some modest chances for non-Thieves to try their hand at some of these abilities; it's possible, but not something to rely on...
