Guide Map-
A Fiery Caper-
To start Lost Her Marbles speak to Darren Lightfinger in Thieves' Guild located in the cellar marked on the guide map. He will tell you that fragments of solidified fire have been scattered across RuneScape and asks you to pick pockets looking for 32 of them. Tell him that you will do and then speak to Chief Thief Robin who is standing nearby. Ask Robin about the caper, he will tell you the following list of possible characters. Man/Woman, H.A.M. members, farmers, master farmers, guards, Al Kharid Warriors, and the rogues in wilderness rogues' castle. Now it's time to go find these flame fragments. You can only get 6 fragments from each type of character, this means you will not need to pickpocket one of the groups. Rogues are the hardest to get to so it's suggested that you skip them.
32 is the Magic Number-
You can check your progress on by clicking on Buyers and Cellars on the in game quest list. At the bottom it will show how many pieces you have gotten from each group. While searching for fragments you can pickpocket the same character until you get 6 fragments and then move on to the next group. Each groups set of 6 fragments will stack separately, you will need 5 stacks of 6 and one stack of 2. You are not guaranteed to get a fragment every time you pickpocket. Some easy locations of the groups are shown on the guide map. If you do decide to pickpocket rogues they are in the Rogues’ Castle in the North East corner of the wilderness.
A Caper Completed-
Once you have 32 fragments head back to the guild and go over to Darren. Use some fragments on him to hand over 8 fragments and earn 1200 thieving experience. Once the conversation is over speak to Robin to receive a reward. Repeat this until you have given all 32 flame fragments and then the mini quest will complete as you receive your final reward.
Rewards: 5000 Thieving Experience in addition the 4800 experience from handing over the fragments. Better loot from NPCs up that require thieving level 40 or less.
