WG. Prince of oak-woods. Kreckskell

I'm currently playing "Prince of the Woods. Krexshell," and remembering the first part of the prince's adventures, I've become accustomed to secret paths, camouflaged portals, and so on. In general, everything was going surprisingly well, and as I naively thought, easily. I quickly eliminated all the enemies until I encountered the main characters in the scenario – the necromancers.
Why, why did I forget the advice of the experienced Marmot again? Why didn't I save more often? As always, when you mistakenly think you're strong, the saves are very far away.
