God of War · Progression system
Combat Skills
Kratos and Atreus each have skill trees of combat abilities unlocked with XP, with further skills becoming available as weapon levels rise.
How it works
Skills include moves such as combos, charging attacks, and active attack buffs. The guide says both characters have their own skills, available to unlock at the start, and that key items that boost weapon level eventually unlock more skills from the tree. XP earned in battle is used to learn combat skills. The supplied source says players eventually earn enough XP to unlock every ability, but does not enumerate individual skill names or costs.
