The goblin in a mask is probably a shaman..., but the orc with a sword and shield turned out much worse... his fingers look like a head.... in general, goblins and orcs are just as ugly as peasants (+ they have some traits of swordsmen and archers), and some demons...
Regarding the upgrade, there are many options, you just need to use your imagination...
For example, here's an elf. You can upgrade archers like this:
One shoots twice (the existing one), and the new one, for example, shoots once, but has more armor or health...
You can make one inquisitor a combat unit, and the other more of a mage. Make a bald mage, and the one with the helmet looks more like a combat unit...
You can leave the existing mage as a druid, and make the second one a werewolf...
In general, you can change either stats or skills, or attack and defense.
You can come up with many ideas, you just need to use your imagination...
Since you don't like the buffalo, suggest your own animal... something that would suit the barbarians... )
And it would be better if everyone had horses, like in the 3rd part...
The woman upgrades into a woman, not a man, she's just masculine... look closer )
Magnus, why are there 5 good races? Do you consider barbarians to be good because they fight against demons? )))
P.S. and in general, maybe this is a beta version... the monsters may still be changed... )
