As you get started in The First Berserker: Khazan, the skill trees can be a bit overwhelming while you get used to how things work. There are four main skill trees to choose from, with three weapon trees and a common skill tree that includes global or general skills that Khazan can use for any weapon. The three weapon types are Dual Wields, Spears, and Great Swords, and they each have skills that are unlocked incrementally as you increase your Mastery Level, which extends up to Mastery Level 34 for the best skills in each tree.
