We goofed around to the fullest).
In the end, Tower showed up with Ciele in the tavern, I decide to play, the opponent had no resurrections.
The first week I mess around trying to level diplomacy on Ciele. And on the second week Vidomina arrives, that's when the necro show really starts, I finish off the mini treasure zones of neighboring respawns, and run to the central treasure zone, with 450 skeletons, take the Dragon Utopias, boost my stats.
At the end of week 4 I catch diplomacy on Vidomina, almost immediately level her to expert, and then just run around recruiting everyone in sight.
At the start of the second month, thanks to the underground cartographer, I manage to reach Ivor, but he offers a surrender, after a roughly equal exchange. I observe major problems with morale, so I wear the pendant +3 morale +3 luck constantly, even considering the Angel Alliance is almost assembled (only missing the hat, which I never found by the end of the game).
Vidomina has full control, mana never drops below 500 (the Dungeon villages provided enough). Implosion deals 5400 damage. And stacks of 100+. Half the army no longer fits in the slots, so I leave 1k skeletons, 20 Hydras of Chaos, a hundred gold golems, 50 Master Genies, etc. in castles or give them to scout heroes. And with the power visible in the screenshot, I run to visit Ivor, he attacks himself, on Firebirds, blows up Efreets by -30 units, tries to buy his way out, but this time I have the Shackles of War - he surrenders.
Diplomacy came to my opponent very late, I had a huge meat advantage.
Thanks for the fun game!
