I played as the hero, completed it in about 4 months, but not entirely. After unlocking and taking the second garrison of brown units, it says that the quest is not completed and the game freezes. And only two quests remain - to defeat Tolgar and capture his castle. In general, it's some kind of mess, or is it just me? In general, I liked the map (scenario, balance of power). However, the main character is not impressive at all. When developing, I focused on dark magic, fortunately, there is a mentor and alchemists (by the way, one of them is inaccessible in the Dungeon). Before the game freezes, the computer says that my hero is stronger than the enemy. And also, I struggled a bit with finding the rune; it could have been helpful to provide a hint.

Replaying the battle with the garrison doesn't help, but the AI speed does. But then Tolgar runs away, which means the quest fails, and in Tor-Hralle, there is a strong Kari with dwarven armor and immunity to Dark magic, which is impossible to defeat. In general, it's not getting any easier.
