They are notable for their use of huge, double-handed swords and katanas.
Heavy Blades are among the three strongest classes due to their ability to equip the heaviest, highest level armors. In terms of physical attack growth, Heavy Blades lose only to Heavy Axemen. They generally have higher physical attack and accuracy than their one-handed counterparts, Blademasters, but they sacrifice attack speed and defense growths in the process.
Heavy Blades have four different types of skills. Two are accessible when using Katana type weapons, and two can be used when wielding other types of swords. While powerful, their skills are limited by their small number of hits. Also the elemental attributes of their attacks are limited. Heavy Blades are only able to make use of the Fire, Thunder, Earth, and Wood elements in their attacks.
