I was trying to get the Godslayer achievement, so I played a game with Amurites and added the Illians as one of the AI civs. Everything was going well at the start, the only entrances to my starting area were two chokepoints which I blocked with forts. The Illians were near those chokepoints and the only other way leading to the Illians was a another two tile wide chokepoint which I block with another fort.
I got lucky with a lair and got a Spellsword which recieved the totaly overpowered "heals +30% after combat" mutation a few turns later. The Illians declared war on me a few times, but they didn't stood a chance against that Spellsword and all the fireballs with movement 5 (Hydromancer trait is great
) from my mages and tower mages. I simply defended my chokepoints without attacking the Illians cities.
I was going for full research, meaning Tower of Complacency, City of a Thousand Slums, Crown of Akharian and mass cottages on floodplains in my capitol. After I had finally researched Divine Essence and Omniscience I gave all those techs to the Illians so that they could build Auric Ascended. At this point I realised that Omniscience can't be traded. So I figured "ok, how long can it possibly take them to research it themselves?" and gave them all my other techs as well to make sure that they were going to research Omniscience asap.
After building the Eyes and Ears Network I saw that they were indeed researching Omniscience but it was taking over 100 turns! At this point I decided to fix the "bug" preventing me from giving Omniscience to the Illians and edited the XML files to make it tradeable. However, at this point the Illians had already completed the Draw and thus were at war with the whole world.
So in order to finally give them Omniscience I first had to make peace with them via the Seven Pines (this is technically a exploit I assume?). Those were at the other side of the world, near the D'tesh capitol. Thus I sended my best Immortal, a settler and some other units out to destroy the D'tesh city and claim the Seven Pines for me, while defending my lands from all the Tier 4 units the Illians were constantly throwing at me (thanks to the techs I gave them
).
My plan worked out, I razed the D'tesh capitol, founded a new city right next to the Seven Pines and used them to make peace with everyone. And a few turns after I had given Omniscience to the Illians they completed Ascension and the event where Kylorin tells me the location of the Godslayer pops up.
Some time later (after checking the whole map with the world editor) I realise that the Godslayer event must be bugged, it didn't spawn. The whole game (500+ turns on epic speed) for nothing.
