The gameplay of Heroes VI mainly follows in the same vein taken by its predecessor, i.e. hero-based faction-affiliated development. As such, every faction has two types of heroes, every unit has an upgrade and turns affect combats as they affect the general gameplay. There are substantial changes, however, and these include the replacement of magic guilds by the creation of spells/abilities wheel, in addition to the skills wheel. New affiliations called "Tears" or "Blood" appear and play a major role in hero development, notably influencing their skills. For instance, a "Tears" affiliated hero will have more defensive/beneficial buffs and his or her reputation will allow for more peaceful negotiations between potential enemies. A "Blood" affiliated hero, on the other hand, will profit from destructive/dark abilities and gain bonuses in adversary combat aimed to hurt the opponents.
