While God of War is hardly a game of min-maxing, knowing how the game's stats work and taking advantage of them can help you to tackle harder difficulties such as 'Give Me a Challenge' and 'Give Me God of War'. Not every stat is vital depending on your playstyle, such as Vitality and Luck, but having at least a bit of each will go a long way toward giving Kratos the boost you need to get through particularly challenging fights and boss battles.
