Which faction poses the greatest challenge for the Dwarves?

Well, there are dwarves who follow the path of light, and there, fistfights and more take place))) Mish-gan, do you like berserkers among the dwarves??? They really look like boxers, only with brass knuckles)))

That's right! And light is mainly used to enhance hand-to-hand combat – punishing strike, stone skin, divine power, especially when it comes to Helmar!

You guessed correctly!
I always keep berserkers for the endgame; in my tactics, they play the role of dark horses. For example: if they aren't taken out before the enemy gets within their range, then... it's game over for the stack that ends up within their range!
The last time I played against Wingael, after his first cheesy attack, almost all of his troops were standing close to mine, with his 17 emerald dragons closest to my berserkers. My friend almost had a heart attack when my 126 boxers, under a rune and with the berserker ability, delivered a double successful attack and wiped out all the dragons!
Try it; it's just an insane tactic!
