Dwarves are generally an overpowered race. :D
In a battle between armies, i.e., when all 7 stacks are filled, during the turn of the Jarls, we apply a rune to them, which allows him to attack twice. He teleports and, before anyone moves, attacks twice (and if luck is also upgraded, you might as well give up).
And lightning strikes twice across your entire army, after which less than half of your army remains. Isn't that cheating? This is just an example of one rune; there are so many other overpowered runes. :cool:
But if we stick to the topic, their ability is the most valuable, and therefore probably the most attractive. At least, I like it.
