This page of the Divinity Original Sin 2 guide contains a detailed description of Rogue. You'll get acquainted with the basic information on this class, recommended playstyle, as well as its biggest advantages and potential disadvantages.
According to the common motive, Rouge is a class that combines high agility with endurance, and fights in close or middle range. Appropriate positioning also plays a part, so you can use the backstabbing hits as often as possible.
A good Rouge also has a high Wits modifier, which allows him to deal critical hits more often. The first parts of the game can be difficult resulting from the lack of a good weapon, but in the longer term, the rouge is a mainstay of the party.
You can find the base parameters for this class below.
Rouge has two enhanced attributes by default:
Silent elimination of enemies requires dexterity. A large bonus to finesse will allow you to deal more damage, especially that most of rouge's tools are scaled according to this attribute.
Additional point that increases health points is useful for a character that focuses on dealing damage at a short distance instead of on endurance.
