I finished it at the end of the second month. The tactic is as follows: after exiting the portal, we run around with Glory, waiting for a wandering red hero, and Rosalía provides reinforcements. There will be few losses. Next, we attack Karl, and then, gathering more troops, we attack István. After that, we gather our forces and head to Valeska. We defeat him with minimal losses. Glory runs towards Gerhard, picking up the Centaur Bow along the way. In approximately two days, Eduardo will emerge from Gerhard's territory. We don't attack him; we attack Gerhard. I have 37 Novices, 99 Guardians, and about 40-50 Archers left. Voilà!
