Iorwerth workers are workers that roam around the Iorwerth Clan district of Prifddinas. They can be pickpocketed with level 91 Thieving (Or 87 Thieving with the use of an Abyssal lurker with Abyssal stealth scroll), continuing the pickpocket action without need for reclicking until you are caught. Each successful pickpocket rewards 125 experience, or 150 experience if the Voice of Seren is illuminating the Iorwerth district. After you have been caught three times, you will not be able to pickpocket them anymore for 20 minutes. During this time, their pickpocket option will disappear, and a grey circle will appear above their heads.
