Thieving is a skill that allows players to obtain coins and items by stealing from market stalls, chests, or by pick pocketing non-player characters (NPCs). It's among one of the easiest Dreamscape skills and is a good money maker for new players.
There are some locations where you can thieve such as:
Home South of Bank (thieving stalls)
Rimmington (thieving stalls)
Ardougne (pickpocket guards)
It's acknowledged that auto clickers are used by many players. Dreamscape is therefore somewhat lenient with their use, with a stance that auto clickers may be used providing the player stays at the computer.
Players caught AFK auto clicking may be penalized with the risk of a ban.
