Players earn skill points as they level up, which can be used to unlock and upgrade skills, allowing for a highly personalized and flexible skill system. All skills have a maximum level cap, though there are methods to exceed this limit. Players can assign unlocked skills to hotkeys via the skill panel for quick access during combat. In all skill trees, progression is linear: players must acquire prerequisite skills before unlocking subsequent skills connected by one-way arrows.
