Walkthroughs for custom maps.

Perhaps I won't delve into that. Maybe reducing the liches' defense to 0 with a destructive beam and then attacking with a stack of demons with a fire shield applied would help? Or using the retaliatory fire shield of the Ifrit Sultans (if they even exist on the map). And replenishing losses with cloned Archangels. Perhaps the author has some kind of plan after all? I just checked the author's description included with the archive, but it contains almost no hints, and nothing is said about the final battle. Maybe something was mentioned in the map's events?
The map's author is Hans C., who also created "The Lone Knight" and "The Uprising." I completed the first one (the report is published here), and I plan to play the second one.
