Not a lot of people will be able to recognize this cosplay… Unless they’ve reached level of their scout (I believe it’s level 84?).
The female scout is the healer of the game. She is a valuable character (unless you don’t mind having to spend a lot of vis/game money for potions). She can also use daggers in combat, but most people use her for her healing abilities and buffs. Some people even say that a scout’s buffs can be a lot better than a wizards’s.
The only thing I’m not too sure about is the color of the costume… I think the default color is red, but there might be some options in the game in order to change her outfit orange. Beautiful detailing, I would say.
