The knight is a melee-based class, specializing in close-ranged attacks.
Initially knights have minimal AOE capabilities but quickly evolve into a multi-targeting machine. With skills that allow you to immediately apply a massive 'Thorns Damage' effect, Whirlwind, and massive AOE stuns. The Knight is the more commonly played class and offers the ability to dual wield weapons upon reaching level 55, and also become immune to damage for a short period of time. Overall the Knight is a very well-rounded class.
