Dual Weapons are known as Dual Wielding, they are real good with delivering a Flurry of Blows as you tap repeatedly with the Z Button, they have Great Critical chance and Attack Speed but lacking in Power and Durability. you can use this to Take Out any Type of Mage, and deal massive damage, also Assassins favor this Dual Wielding. but these weapons are good dealing with Behemoths, Mages, Grunts, and any other type of enemy, but except for defenders because they can carry a lot of armor and takes a long time to kill defenders, you have great speed and mobility to dodge any attack. so good luck
