Creating your own hero.

We take a hero, in the object's property tree, we select "Shared" and click on "...".
In the right part of the newly opened window, we are interested in the HeroCharacterArena and HeroCharacterAdventure properties. For each of them, we click on "..." and select the Minotaur (Characters\Creatures\Dungeon). We don't rush to close the window: the Minotaur lacks animations that heroes should have. We select ArenaAnimSet and click on "...". For complete happiness, it lacks buff, cast, defeat, and victory animations. We right-click on animations, add in the opened menu, in the kind field, we write the name of the animation that we don't have, and in the Anim property, we copy the value of this property from some other animation (to taste). That's basically it. The only problem is the melee attack, because our Minotaur, in theory, cannot shoot. Unfortunately, standard creature animations are not suitable for melee attacks, so I can only suggest adding rangeattack to the list of animations above for shooting.
