Sometimes trebuchets are not the best solution to city sieges depending on spells/city enchantments/defending units the enemy has. Of course, you can also opt to “tech up” the Kir’ko branch to get Tormented or Harbingers, but I found that I was winning games on higher difficulties without even doing that.A few questions, what class are you playing as? Any different settings (besides difficulty)? What turn do these battles usually happen on? Do you have any screenshots of the army compositions for the city battles? To see army composition. Naturally, you’ll want to give them some Bio-based mods too.

Have your mutation units following around as support for your main army, auto-resolve a few battles with neutrals, and watch those higher-tier units magically appear. Many battles that you win, even when auto-resolving, will spawn Pustules, followed by Destroyers and Plague Lords. Since we’re using cheap melee units, we can focus primarily on the Xenoplague secret tech’s unique bonuses such as mutations. To be frank, the biggest challenge you’ll have would be against flying units, so you’ll want to bring some ranged or air units along as support (Kir’ko Hidden), unless you want to “spit” all day at wyverns. Stack them up to gain more Swarm Shield benefits while they regenerate (and/or explode) each turn. One doctrine will increase the chances of spawning and upgrading Xenoplague creatures, and the latter (which is unnecessary given your regenerative capabilities) adds healing after battles for every biological enemy you kill.Īlong the way, your cheap early-game units will serve you until the very end. Next up would be the Xenoplague-specific Bio-Matter Repurposing. The doctrine (Preserving the Future) and the colony building upgrade (Brood Cluster) are a must for your expansion and unit production. Obviously, the first one to grab is the unique tech for the Kir’ko which is Nurturing. Society tech tree choices are fairly straightforward. Imagine the enemy taking forever to kill a single Kir’ko Frenzied and then dying if they try to keep doing just that. The latter will revive that unit if it dies (retaining the Poison Excretion mod’s effect).

The former will have adjacent enemy units taking Bio damage, and your own unit can explode on death, causing even more mayhem. Much later, you can apply the Poison Excretion and Resuscitation Glands mods (from the Infection and Neogenesis techs respectively).
