Good map, needs a little tweaking and it will be great!
It's unclear how to collect the Dragon Artifact set - I couldn't find the greaves anywhere. I studied the map for a long time, so when I reached Vaish, he was one and a half times stronger, with 200 dragons, etc. And dark magic at the start for the main hero is like a fifth leg for a dog; they didn't give any decent spells in any of the 5 castles! If I had known, I would have leveled up Chaos).
2. Dark magic is given by the computer (initially); I added luck (it is very common among the forest elves). You can't remove magic, but there is something to level up when they offer garbage.
