I wonder, is the Book of Water the "ready-made solution" for destroying the Azure faction?
I want to be criticized, but I went with skeletons and Galtran, and that's how I take Utopias (the main intermediate hero who does the main dirty work and strives for the main artifact. And the arena hero suffers from nonsense, eating and collecting Archons). One downside is that he moves very slowly. This is essentially the only problem, but with all the consequences that come with it :(. All hope rests on the liches. For their sake, I abandoned the Titans and ignored the evil computer.
The quest has a restriction that you can't take "skeletons" to the arena. Taken literally, so liches will be taken! :)
I didn't find anything more suitable either! The Book and Archangels. You can also take cows and get free resurrection on TE, but I prefer the Book. And probably a berserker and a vulnerability sphere!
That is, there is a lot of choice. Or you can just not rush and take them at the end of the game.
Galtran is quite possible as the main hero for those playing on TE, since you can only not take skeletons from the transformer to the arena, but those obtained through necromancy can be taken, as well as liches or zombies.
The main hero's task here is really to run around and collect bonuses, but the companion still needs to be used to build up finances in his castles.
Liches are good, but they need to be obtained using wings and a chain of necromancers!
