Each city type has two different uniquie hero types: A Might and a Magic Hero. A Might Hero tends to have higher Attack and Defense, along with more martially inclined abilities. A Magic Hero is more magically inclined, and comes with a spellbook. Furthermore, each hero type has about eight different unique heroes, with thier own skills and specialties. In any section the Might Heroes will be listed first.
Name - The name of the Hero.
Race - The race and gender of the hero. Doesn't really have an impact.
Specialty - The Specialty of the hero. Specialites are non-skill abilities that can either generate more resources, raise the hero's effectiveness with a certain creature (For every level they gain above the creature's level) , raise the hero's effectiveness with a certain spell (In relation to the difference between the hero's level and the creature's level), or grant a bonus to a skill they have (At 5% per level). As can be seen, most specialties are heavily level based. It's also worth noting that a hero with a non-resource specialty will always have what they specialize in to start out (and the nessecary spell points for a spell specialty)
Skills - What secondary skills they start with.
Stats - The starting stats of that type of hero, in the Hero Stats section.
Stats % (2-9) - The chance of raising a particular primary skill when a hero gains a level between 2 and 9, in the Hero Stats section.
Stats % (10 +) - The chance of raising a particular primary skill when a hero gains a level from 10 onwards, in the Hero Stats section.
