For example, some heroes cannot cast spells themselves but can use magic scrolls to achieve their goals; such heroes do not need mana, as each scroll contains a sufficient amount of power. However, scrolls can be used a limited number of times, and most only once. Others can cast spells on their own; it is enough for them to learn a spell so that the mage can later use it an unlimited number of times, but such heroes are limited by the amount of mana, which regenerates very slowly. A third group has no magical abilities at all, but strength and tactics make them equally dangerous opponents. Different heroes affect the creatures in their army differently, and accumulated experience also impacts them in various ways.
