Walkthroughs for custom maps.

Yes, and it's quite a radical change. I've developed the idea of differentiating difficulty levels: some critical artifacts (Sphere of Vulnerability) and spells (Clone, Berserk) will be given much later, by 200%, so some battles can easily turn into a Chinese folk game – "wait 50 turns while the AI uses up its shots and mana."

I'd like to suggest a small addition for the map – remove such a large number of random, non-plot-related artifacts (there are almost ten Unicorn Helms, Legion Boots, and other Centaur Axes – it's a pain to sell them all) and also, maybe I just reached it too late, but the undead enemy you fight after opening the gates with the Gravedigger's Amulet (with skeletons and zombies) is quite weak – his army needs to be buffed.
By the way, based on my experience, the Cursed Armor isn't really needed for the garrison with Black Dragons; everything can be completed easily, so it could also be given later.
And regarding the "Chinese folk game" – I don't really like battles where you do the same thing for half an hour (Power Field, Berserk, Power Field, Berserk...).
P.S. Thanks for the map!
