Walkthroughs for custom maps.

You've really gotten into it. I haven't played in the last few days, so my results are more modest: I've played for six months, I've also freed Jelu, I have the mentioned spells plus frenzy and teleport, but I don't have clone. Did I learn clone from the computer or was it available in the guild of the tower village in the lower right corner of the land part of the map? The Moon has sailed to the orange player (I'm waiting for the orange player to get me the last artifact from the Titan's Thunder set in the water), and Sir Mullich has almost sailed to the pink player. I haven't put much pressure on the green and blue heroes yet, because for truly serious battles, I need clone. Accordingly, I haven't touched the brown player yet. And I understand that the computer has gathered all its flag resources on Thorgrim and Kilgor?

Map 6424 Heroes
It's been a long time since a map has captivated me like this one! I agree that the map isn't as difficult as it seemed at first. I got all the spells with ease, and I didn't consider other options (since I'm playing as Jelu and he knows resurrect). For this (spoiler), it's desirable that the blue player releases a couple of heroes from the prisons, then they will consolidate the army on one of them, and give the rest a legion of wolves and/or archers. With such a small army, the "weak" blue player, under slow, casts clone, teleport, armageddon, resurrection, etc. It was in battles with these "weak" players that I got teleport, clone, resurrect, and prayer (I don't have frenzy and armageddon, but that's not a problem). It was very easy to get, I should note, in 2 battles in a row over 2 game days! :)
Another tip for battles. With 500-1000 bears under clone, they can defeat any blue or green player. All battles are the same: the computer attacks any forces, except for the bears. The bears, with their clone, kill the larvas + any stack (dragons, unicorns, etc.). At the same time, they severely wound (up to ten or twelve) archers or units that don't retaliate, we resurrect completely, and after resurrection, we kill the rest. Thorgrim and all the green players were killed VERY EASILY using this strategy, both in the castle when defending and in the field. But you need clone for both the bears and for the resurrection/clone of archons. Without clone, the battles become much more difficult. At the moment, Thorgrim has already been killed, and soon it will be Kilgor's turn.
On the other hand, it is desirable to avoid the complete consolidation of forces on one player, as I imprudently did with the purple player. Now, Xiron is riding with 1,600 archdevils, over 4,000 ifrits, and about 250 larvas, and this is much harder to kill....
