Even a hero can sometimes stray from the path of righteousness in order to gain experience and serve the greater good. It is better to hide your true face when robbing people in the online game
In the course of the storyline quest “Rabid Bull Affair” the chief of the Long Knives hands you a curious black mask. It is a valuable tool, if you are planning criminal activities.
This mask will allow you to remain invisible and obscure your identity if you decide to carry out a theft and intimidate those you plan to rob. But use it wisely and sparingly, because while you are wearing the mask, many people of Haradan will only see you as a robber and refuse to talk to you, let alone give you assignments.
The Thief's Mask also acts as armor in combat, but be careful! If it is damaged or destroyed you will not get a replacement.
Only if the Long Knives gang trusts you enough will you be given the chance to purchase an Elite Thief's Mask in the Robber's repository. You need 7000 Long Knives reputation for them to let you buy one. With this better version of the mask your robberies will give you greater booty.
