Damn, I didn't even go into the treasuries or pyramids =( I didn't think about it.

If you're playing on a high difficulty level, you'll have a hard time in the 5th mission. Don't even think about ignoring the treasury and utopia in the 2nd mission of the next campaign.

2 Boris_K, it's not Agrail, it's Markel))) you've made a typo in two posts in a row))) [/offtop]

And I had Isabel leveled up through Darkness and she cleared the right half of the map (it's easy with Subjugation), various islands... While Markel, after clearing out a few respawn points, went almost immediately to the mages, and also gathered some troops at sea (again, Darkness in patch 1.41 is a complete evil. I didn't even level up Summoning for the Necromancer, only later towards the end of the mission for the Phoenix, I invested three levels).

Of course, it's Markel. :) I've mixed up the names of the heroes more than once. At the very beginning of the mission, Isabel and the supporting hero quickly gathered everything that was floating around. Then Isabel walked next to Markel, picked up useful items, and carried troops that were temporarily unnecessary for Markel. Sometimes she hid in the monastery. I was very afraid of losing her. The Knight's Castle in this mission is weak. She couldn't build a serious army. Therefore, what was being built there, I converted into undead for Markel. And how does Darkness in patch 1.41 differ from Darkness in other versions? In 1.5, it seems to me, it's exactly the same. Light against Darkness is also good in skilled hands. In the 5th mission, Godrick used Anti-Magic to remove Subjugation and Berserkers.
