Notes: Can charm NPCs to give lower fees, ability pick cat colours, change Fremennik name, and more. Refer to our Charos Charming guide for more information. If the ring has been lost after completion of Garden of Tranquillity, pickpocket Dr Fenkenstrain who should be locked up in the tower of Fenkenstrain's castle (on the roof) near Morytania. If Great Brain Robbery, The has been completed, you will have to travel to Harmony Island from Mos Le'Harmless (speak to the hooded monk close to the docks) and go into the cellar of the windmill to pickpocket him. It also halves the price of chartering boats and makes trips to Port Sarim, Brimhaven and Musa Point free.
