An epic game.
There is a way to beat it in one or two playthroughs without using cheats.
First, when choosing heroes, set the main skills for the selected classes to the maximum of 25 (for example, for the Paladin, this is strength, stamina, and will; for the Mage, it's intelligence). Compensate for the lack of points by reducing "unnecessary" skills (for example, set the Mage's strength to 7, etc.) - you can still raise them to 15 in the wells later (but you won't be able to raise the Paladin's strength to 25 in the well).
Then, in Sorpigal, quickly complete the quests with the Goblin Tower and the Lantern in the Baa Cave - and on the same Monday, go to Ironfist so as not to waste 2 days. There, do what you usually do: buy bows, train experts, etc. But don't hesitate to spend 200 coins - hire a Gate Master. And go to Free Haven. Here, there's a well to constantly increase strength (on the next visit, the "weaklings" will already all be at 15 - you can pray at the Altar of Strength in January, but without the Gate Master, you probably won't have time). Plus, 8 horseshoes.
Level up the Mage to Water Expert and buy Lloyd's Beacon. That's it. After that, place beacons on the wells, which give +50 to all skills, +30 to level, etc. After that, it basically becomes a slaughter.
Yes, and one more thing. I assigned features like trading, identification, repair, traps, etc., all to the Paladin. He has few magic skills that points are spent on. And it's better to use the "saved" points to give the Mage and Priest magic of light and darkness. Combined with Day of Gods and other spells, the squad turns into terminators even at early levels.
