The map is good, I really liked it, but it's too easy even on Hero difficulty.
Among the drawbacks that weren't mentioned, I'd like to add:
1. I played on Hero difficulty, and the Joker appeared in the first week. I "took" him and didn't see him again.
2. The Necromancer's helmet is guarded by hundreds of Cave Lords. Honestly, I captured the garrison without any losses, and it was easier than dealing with the Lords.
3. At the start, when you get the Necromancer's helmet, you have the opportunity to get a bonus artifact, and this helmet can appear. There's also an artifact shop. In my opinion, the quest needs to be reworked so that you have to kill strong neutral creatures, rather than bringing an artifact.
