I suggest we make the thieving sack untradeable and have the ability to hold up to 7-14 items received from a pickpocketed NPC. Kind of like the beginner clues with the Tramp(Make him a dagger or craft him something). It would register similarly to that when you pickpocket the item. Then you’ll have the ability to add it to the Sack.
Idk, what is everyone’s input? I think the skill should have a unique item.
