Walkthroughs for custom maps.

Desaved, I looked at your map right away... for about 5 minutes. I'm personally interested in large maps; I didn't try to play through it. For now, I can only make one observation: it's best to fill the empty spaces with forests, mountains, and ravines – it looks better, and it's less noticeable that there aren't many objects. In any case, if you're interested, keep going and develop your skills.

So, I paid tribute to one of the oldest "heroic" hits. I'll write a little more about this map.
Plot: This is the story of the conquering wars of a great barbarian commander named Leondegrance. (Notably, one of the first brutal and "bloody" maps was created by a girl).
Overall, the map is quite good. Its actual difficulty is not very high: players with sufficient experience will not encounter any particular difficulties (and those who do will read the advice below).
At first, to be honest, I wasn't very interested in playing through this map, but it got much better later on. The sections of the path where you only have to control Leondegrance, while the other heroes just stand and wait, are not very interesting. Fortunately, there are not many of these sections, and usually all the heroes have something to do: some are gathering troops from all the cities, some are exploring the surroundings, some are leveling up...
I already wrote that I encountered flying units of the Pink faction: he managed to reach almost the Citadel of Ooresdome - even though his native zones are in the northeast of the dungeon and one city is in the southwest of the dungeon. It turned out that Flight is available in the guild of mages in one of the Necropolises in the northeast, so the Pink faction was flying completely legally. Fortunately, no other enemies flew, and I didn't have any problems with that. (Update: it turned out that I was playing the not the latest version. In the updated, AB version, this problem should not exist)
The last and strongest of the enemies - the knight Gwhenwyfar (Orange) - is the author's pseudonym. It is not easy to defeat her, but it is possible.
My result is not bad: victory on 9-4-3, 248 days, 492 points (the author wrote that the approximate completion time is 300 days).
P.S. After this map, you will love chess! ;)A banal but essential tip. The key to success is regular saves! Save every day, and on some days - several times. You will delete old saves later, but you won't have to regret it if you realize one day that you turned in the wrong direction. The map has enough sudden ambushes and not-so-obvious moments when you need to decide where to go.
After you reach the Fortress on the hill, try to upgrade troops of levels 1-4 in it: for the first time, there will always be many more troops than you can hire!
Capture the outer dwellings belonging to the enemies. This will reduce the growth in their cities, and in addition, in the 4 swamp cities, a considerable additional army will gradually gather, which can be hired when there is enough money for it.
Since you capture at least one Fortress, try to take at least one monster with you that is faster than the barbarian ones: dragonfly, black dragon, archdevil, archangel.
Tips with spoilers for those who are experiencing difficulties, I decided not to publish yet: they turned out to be quite detailed; this is more of a story about my playthrough of the map. If anyone needs them, I will write them.

Update: Attention! I found (and replaced in the collection of the best maps) the updated, AB version of this map (in the attachment)! Everyone who previously downloaded the old, RoE version should also update it!
