No, battles always take place on the battlefield. For the Dwarves, I also upgraded their Combat Alchemy (CA) + attack with an attacking hero and retribution, and leadership. I don't even know if the Dwarves could withstand the first wave of attack from the Elves if they had, say, a complete set of Dwarven artifacts. Because when I was fighting for Inferno, 900 of his units immediately rushed into attack and completely wiped out 3 of my stacks of not the weakest units. The stats were also roughly equal.

The Dwarves' CA completely negates the Elves'. Then they get stuck on your strong front ranks, and that's it; they don't kill much. In the next turn, you use runes that heal your front units by 40% (I don't remember exactly), and then under the runes, you destroy everything. If he risks sending dragons, even if they attack twice, they will then receive a guaranteed one-shot from your dragons under the runes. And if you also have a set that provides two mass buffs for defense and evasion, then even the archers won't do anything.
