Tactics for the Swamp (Fortress).

Generally speaking, everything is correct, but there are a lot of ifs in your post.

By the way, taking a Dragon Utopia in week 2 is a utopia :-)
Even if it's the simplest one. (well, in theory, of course, everything is possible, but in practice it's hardly feasible)
If you get lucky in week 4, you can put in some effort — earlier is unlikely.

Forrest (red, Necropolis, Galthran) def vbn (Rampart, Kyrre), TE, 2sm4d, 1-3-2

Interesting game! and especially the battle!!

The opponent took Rampart, I took Necro (just like the hogs! even though there's no necromancy, but Galthran is an analog of Shakti.)

I took all the restarts. Generated a simple template, and slow roads.
Started playing. I find external dwellings: 3 skeleton ones in the first week and one peasant (Horde of Corel Griffins) — I take all of them. I reach level 7. Liches in the citadel. Could have tried for the consa too but why bother when I have skeletons :p

Plan is banal. Take the Utopia as soon as I reach it (on the respawn) and rush to Kyrre. The respawn was huge, which slowed everything down a bit. I take the Utopia on 1-2-4, tier 3. It didn't give much. Tome of Earth, Plate, and Dragonbone Breastplate. I'm at 13-10-5-3. I hide the Plate — not enough knowledge. Monere, meanwhile, with an angel, knocks out tons of gold and secondary skills. Buys a host-dragoon from the mercenaries. Finds the Griffin Conservatory trong. (Took the tier 2 one immediately on the second week)
I FINALLY FIND THE ГО. One Azure. (3 days away with expert logistics from my home :) ) I kill it on 1-3-1, take a look and see where Kyrre is sitting. I check his army. Hm.. quite a bit — 15 unicorns for example. I decided to replenish mana — the well is visible. Meanwhile, bring 21 vamps, an angel, and a dragoon from Monere. If they get repelled, plan B is to take the conservatory with vamps and from the treasury that Monere found.
But Kyrre apparently couldn't stand it and attacked himself.
Kyrre 6-5-6-1 (10) 15 unicorns, 41 grand elves, 25 pegasi, 15 dendroids, 41 war centaurs, 4 re griffins. 3 Green Dragons.
Galthran 13-10-5-5(29) 205 war skeletons, 13 liches, 23+23 witch greys. 4 re horses, 3 dragons, an angel. Expert offense, armor, earth. That's what decided it.

Kyrre expert tactics (has advanced), cements the elves. I wait with angels, he waits with greens. I cast Slow on everyone. The lich pile shoots. The witches drain mana from Kyrre just for mass shield.
In the end, my army under shield and skin approached and piled on turn 1. I managed to win in round 7. GG. (survived: 36 witches, an angel, a dragoon, 4 re horses, 141 skeletons, and 9 liches)
Thanks for the game 1-0
