Death (ghouls, vampires, bone dragons)
Order (mages, djinns, titans)
Chaos (medusas, horses, black dragons)
Nature (elves, griffins, phoenixes)
Might (harpies, cyclops, monsters)
Ballistas, monks, mages, titans, elves, cyclops, medusas – I chose these because they defend the castle from the towers and cast spells.
Harpies, phoenixes, and mantises, black dragons, djinns,
vampires and bone dragons, angels – I chose these for speed, but the hero always had combat skills and magic resistance 5, ranged and melee combat 5 + life magic 3 + some other magic 5, so he didn't need an army.
