A good pace was achieved by quickly gathering air elementals on the main hero and earth elementals on the support hero. I decided not to delay and headed towards the opponent's main base, along the way completing a quest (8 gold for necropolises). I positioned myself in the darkness to capture a castle, but the opponent still skillfully thwarted my attack with scouting and fortified his main base with a citadel. I had a much larger army advantage, so without hesitation, I attacked.
Thank you for the game!
I decided to go in a different direction. Before attacking the main base, I captured a relic from Solmyr, but it turned out to be insufficient, as the army advantage was much greater than I had anticipated. It's a pity that the mephit and golem didn't acquire the desired skills in the form of magic or logistics.
Thank you for the game.
