Yeah, IMHO, Master's maps were somehow easier to complete...
The quest to provide reinforcements to Tilsek has been completed. After that, Gabriel arrives with a huge army, and Victor emerges from a portal (it was mentioned in the previous post that the portal would close after completing the quest). Gabriel goes first, duplicates 357 griffins, and then things get really bad. She doesn't want to fight in the Castle. IMHO, the map can only be completed a) with luck (in both my Castles, I didn't have any Screaming or Horde of Rage) and b) with a very high player skill level. As already noted, the difficulty level doesn't matter - I played on Recruit just to avoid worrying about resources at the beginning.
As always in such cases, the question arises: why did the author put in the effort, bother with scripts, and come up with a plot? How can you find time, for example, to complete the quest with the mage if you constantly have to jump back to the Castle and defend yourself?
I think I won't try to complete the scenario in this version - it's clear that I need to grind again (worrying about every first battle), get the necessary spells in the Castles, count every move - knowing in advance what needs to be done, etc. In order to eventually overwhelm Clara with brute force, skipping half of the plot and quests.
The reinforcement quest has two stages, and after each stage, you need to wait a certain number of days while, let's say, Tilsek deals with everything.
And please don't torture yourself; it seems that this map is not for you.
I'm now just thinking about blocking the portal to the city for enemy cities, at least
