Faction and hero.

Might — strength; the higher it is, the more powerful the strike against a monster will be
Intellect — intellect determines how large the mana pool will be for dragons, dark elves, and Necromancers
Personality — charm; personal qualities are very important for clerics, minotaurs, and vampires
Endurance — endurance; a universal and very important characteristic for all heroes, as a large reserve of vitality is necessary not only for a warrior but also for a mage
Accuracy — accuracy; affects the hit chance of both ranged weapons (bows and crossbows) and melee weapons.
Speed — the higher the speed, the less time passes between a hero's attacks. Also try to develop skills in shields and armor so that they do not slow down the hero's actions.
Luck — a somewhat mysterious characteristic; luck has a small influence on many game events. For example, high luck improves a hero's resistance to magical attacks and reduces damage from triggered traps.
