Light Fingers increases your chances of successfully pickpocketing. Your chances at each level are listed below (if you are playing a Khajiit, add 5 to each of these values). Note that your chance may be higher if you can get into the "sweet spot" (numbers in green) by waiting a few seconds, or catching them while they are moving around and not stationary. Or it may be lower if they are already suspicious (most likely due to a previous failed attempt). Note that even a Khajiit with maxed skill under ideal circumstances still has a 5% chance of failure against hard targets.
