Demon invasion.

Where should I leave my troops on the 3rd map? They are all mixed up – I have diplomacy. What the heck is going on? You can place them in garrisons, but you can't take them out. All the Castles are blocked by "allies." After getting back to Shio and into the Necropolis Castle, there's no way out. The garrison is impenetrable.

Talk to Kha-Beleth first, and then talk to the Mentor; then it will be clear how to get out. If you need to drop something, there seems to be one unoccupied mine behind the portal near the top Castle, which is guarded by manticores.

The fourth map is definitely tough, even compared to the others. First of all, there's no way to reroll the starting layout because all the battles are roughly like this: , . Therefore, on each reload, I added experience using cheats to understand what they would offer. In the best possible layout, I quickly got the ranged attack skill – I captured the mercury mine on day 6 and the boots after a couple of attempts on day 9. Then I got the building plan on level 13 – the minimum plan is complete. Then I checked – they will offer many good things – light, dark, attack, crafting. And I still need logistics... Ideally, all of this is great, especially considering the Mentor's guard. I'm leaning more towards dark magic + crafting, and then, together with the machines, I'll switch the rest. But remembering the guard of Sandro's cloak, without which the Mentor cannot be defeated (ghosts + necrodragons), a storm would be very useful here. Should I give up on logistics and go for machines/defense/light/dark/crafting instead, especially since I have both pairs of boots on the map. I've never managed to develop a normal strategy for this map in all my previous playthroughs; I've always managed to win based on some random layouts.
