The Azure Knight is the premium tank in 2Moons. They use most melee weapons and can dual weild. Almost every class in 2Moons has an AOE or AE skill and the Azure Knight is no exception. If you want to play a tank in this game then this guy is about your only choice. The agro system in 2Moons takes away from playing a true tank class quite a bit but they can still be useful as a damage taker for group play. Here's a link to the skills and abilities:
