Used all restarts, the opponent only took one. We started playing, the roads are fast, there's a hidden spot with creatures on day 1, a mine near the Castle, and a hidden spot with horses in the distance – good. Fiur arrived, and I immediately started leveling him up; he gets ranged attack. Thanks to Korback, all scouts are on flies. On day 2, using a watchtower, I saw a Grand Order – a horde of Pit Lords, four forks – a Grand Order, lots of Medusas, lots of upgraded Griffins, and a pack of Unicorns: too much for me. Day 3 – a hidden spot with archers, I immediately take them home to upgrade. The scouts are scavenging, and my hero is leveling up. Day 6 – I build horses and immediately send them into battle; my hero crushes the Griffins, followed by the Nomads. The archers took some damage from morale during the breakthrough, but it's manageable. 117 – horses with a Stronghold, Fiur 9-3-3-3. 121, a mine for 1 Angel, I buy a book at home and speed up before the pack of Unicorns. 122, my hero repels the Pandora on the entire third level of magic, takes the hidden spot with horses and the Crypt. A scout with 10 Swordsmen, 6 creatures, and a ballista takes the secondary Inferno Castle. 123, my hero rampages through the arenas and clears the way to the secondary Swamp Castle; the scout speeds him up and, with a bag of gold, takes the Swamp Castle. 124, my hero is at home, replenishing mana, and the army is in the Castle. 125, I build the second level of magic, which includes Blindness... at the end of the day, Fiur is sped up with an Angel before the Grand Order; Catherine with an army is nearby. 126, I break through the Grand Order, moving strictly along the road (I am, after all, an expert in logistics; stables and an Angel at the beginning of the day – maybe I'll reach the Blue Castle and surprise him...), but the roads are messed up, and I don't reach the Castle for several turns. Tazar gathers his entire army and attacks, which was strange to me – I thought I would have to take it by siege, and I probably wouldn't attack such a large force in the Castle. Perhaps the fact that the opponent only had one tavern and didn't know my hero's stats before the battle played a role.
Fiur 17-4-4-4, expert in attack, ranged attack, and logistics, advanced armor, tactics, and wisdom. Army: 1 Angel, 6 Cavaliers, 77 creatures, 30 crossbowmen, and a ballista. No mana left; it was all used for blinding the Pit Lords.
Tazar 2-5-1-1, expert in armor. Army: 2 Angels, 4 Wyverns, 39 Lizards, 14 Basilisks, some Dragonflies, and a tent.
The advantage in stats decided the outcome of the battle in favor of the elemental.
I can upload the saves for each day if you're interested.
