How to unlock the Sticky-fingered achievement in Styx: Master of Shadows - Definitive Guide
What you need to do is find a guard with something on his belt. Save the game. Now sneak up to the guard and when you get close press to remove the merchandise. Wait a couple of secs. Now reload the saved game. Rinse and repeat.
NOTE: You do have to wait a second or two for the pickpocket to register. Simply snap your achievements and go back to the game with the achievements still snapped. Once you pickpocket, wait for your progress to go up. Sometimes the progress won't go up until you move your character.
As you progress through missions, some guards will be carrying an item on their belt that can be pick-pocketed. You will visually be able to see the item on their belt, such as a single throwing knife or a vial. As you sneak up behind them, you will be shown an additional option: (Pickpocket). If you successfully acquire the item, it counts for this trophy. After the 15th time, the trophy will pop. Any successful pick-pocket is immediately saved and counted in your game data. If you die or simply restart, then it is still counted.
I found this ability useless because half the time I wouldn't even notice that the guard had an item before taking them out. The other half of the time I wouldn't be able to perform the pick pocket because I was already maxed for that item. For example: If Styx was already carrying 2 throwing knives and he tried to pick pocket a third, the game will tell you that you cannot do it because your inventory is full. It became annoying enough that I eventually made a save before a guard and repeatedly did the pick-pocket-then-reload trick to close out the trophy.
