So these just help you level-up quicker? If I pick Warrior stone its only giving me bonus points to level up faster on warrior perks? an armor? an If I pick Thief stone then it does the same for lock picking? sneak an speech? maybe why I was stuck on one level for soo long, my last game I played pretty much with warrior stone through out becuase I was under the impression that it gave you an advantage IN Battle??
