A Berserk is a barbaric warrior from the northern parts of the world.
Berserks wield massive claymores that they use to hack apart enemies and in large groups can hack away any foes. However, they don't wear any armour as this would restrict thier movement, which is thier main advantage as they are the fastest runners out of the all the forces of light. As such, they are often used in the role of scouts, trackers and flankers.
Berserks in the past had shared somewthing of a rivalry with the Myrmidons, before the Myrmidons betrayed the light and joined Balor. Now the two warrior cultures are bitter enemies.
