Hand of Fate. Part 2: Despair

The map is great in every aspect, except for the condition that allows you to traverse the desert. I think that either a hint should be provided at the beginning of the scenario, or an alternative way to complete the desert quest should be offered. I arrived at the hut where they give a hint, with a well-developed hero, and all the slots for basic skills were already occupied. I spent a long time trying to remember which skill the Blessing of Ashi belongs to (I had to open the skill wheel – I just don’t take luck, as it is partially replaced by artifacts in combat). Of course, there was no money for a mentor at that time. In six and a half months, I cleared the map (I'm not a super player), and the desert remained – I started experimenting. I tried to go around it along one edge, then along the other (it doesn't pull you into the sand from the very first step). Now I'm trying to get luck from the mentor. I got tired of it; when I forget two skills, the wrong ones appear, and I'm tired of trying different options – I need to train from scratch. In my opinion, this is an outrage, because the hero is well-developed and nurtured, and I don't want to subject him to such violence. In general, unfortunately, I didn't finish the map. It's a pity.
P.S. Or maybe I just missed some loophole?
