Thieves usually inhabit urban areas such as towns and cities and ply their trade by stealing, extorting, and embezzling. Stealth is the main ability of the thief and a good dexterity is essential. Usually thieves are organised into guilds, who maintain order in their town and meter out punishment to those who freelance.
One of the unusual abilities of thieves is the ability to back stab. It is a level based ability as follows:
