Awakening of Evil

1. Where is the blue tent of the key master? I can't find it.
2. The Ents don't work as quests. Why?
3. Where do you get quests? I didn't find anything on the first map... Maybe it's the Ents?
4. I developed in this order: education, magic, attack, logistics, and defense. Because without tactics, it's hopeless. I constantly split up my Fury units.

And what do these circles mean? Maybe they are quests? Mine don't react... Maybe I need to remove the mod?

There are these beige prophet huts, and that's where they give quests, or I've also found them in peasant huts.
So you can level up - there are 3 or 4 mentors here (I've actually explored almost half the map and only found 2).
I leveled up: leadership (troop gathering, speed aura, and gold), logistics (pathfinding, path of war, surprise attack), darkness (all the first 3 for mass spells), luck (magic resistance, soldier's luck, death's misfortune), attack (frenzy, retribution, tactics).
In my opinion, this is the optimal build for this map and specialization
