The Blademaster is one of the two Templar classes.
Blademasters are aggressive, high-damage melee fighters who come into their own when wielding two weapons and inflicting pain with sharp objects. They are often seen running to the front of the battle and causing havoc in spurts, allowing others with ranged weaponary to deal damage from afar and in relative safely. Their skill groups are Swordsmanship, Surge Attack and Auras.
The Blademaster is all about dealing as much damage as fast as one can. It is the only class known to be able to dual-wield swords. The Blademaster also gets a nifty skill called Throw Sword Mastery for hitting those pesky out-of-reach demons.
