Walkthroughs for custom maps.

It has all the potential to become a popular hero game hit if people find out about it.

They already know about it – so it will become one. ;) Especially since

the map has a medium difficulty level, and in terms of its level/quality of development, it can be ranked among generally recognized hero game hits.

And not everyone likes exclusively hardcore games. I also downloaded it for the future. There is a link to the author's article in the description; you can read it using Google Translate.
It is also worth noting that there are very few custom maps where we play as the Conflux. The weakness of this faction: only phoenixes and fairies can be resurrected. But if we have enough cities or external phoenix dwellings, then the power of the Conflux in SoD grows very quickly. As an example, we can recall "Wings of Heaven" (where we have a Conflux with a bunch of external camps and Towers).

a Titan's Roar dropped from the tomb.

Lucky you! :) By the way, I was also incredibly lucky the other day: I found a Mana Talisman in the sea and assembled a Wizard's Well, which I needed literally the next game day (after an event that drains mana).
