Most of the setup is already done for you, fortunately. It does have a learning curve, but they have a dedicated team that will assist you with guides, and videos showing you step by step exactly how to set it up and get your BSN bot up and running within about 10 minutes. It includes options for things like what spells to cast, where to grind, and how much loot you want to collect.
So what exactly is it you ask? Well, the mmoviper team has created a program that will interface with the Blade and Soul game and automate some of the game play for you.
