I’ll try to be quick. I was doing my first game with the vaulter (with all the extension). My civilization was settle on an island, with evil ardent mage at my neighbor, who threaten me for no reason. Because of is brutal expansion, I was only able to get tree regions. At the same time, two unknown faction were competing for the first score. Around turn 70, the mages start to become even angrier, and I discover they were at war with one of the unknown faction who were aiming for the first place. After a little more exploration, I discover we were 3 faction on this island:



My little vaulter empire, with 4 region (3 on the island, and a region in the middle of the sea, who provide me almost nothings)



The ardent mage, with a powerful army, but only 3 regions



And a FUKHUEG necrophage empire, with a gigantic army, and more region than I can see with my little fleet.



I watch the war, and I see the mage throw all they army at the insect city, almost capture it, getting destroyed, and an important army from the necrophage capture two city to the mage, before leaving them without any protection. It goes without saying that I quickly avenge my dear mage brother, and capture the three unprotected city, which greatly increase the power of my empire. Then, I asked for a truce with the necro, because my army was really, really weak. They took advantage of the truce by taking the last ardent mage stronghold, who was in the middle of my empire, and enforce it to the point of putting two heroes in that region. For my part, I knew the war was a matter of time, so I create a lot of unit, buy a new heroes and start praying khorne. Now the truce have ended, and each faction look at the other one at the other side of the frontiers.



If I’m here it’s because I want to know if some of you have good idea to win this war, and the game as well. After some projection, I discover that I can take the old mage stronghold, but it will cost me almost all of my army. Moreover, I know one of the other faction have built a guardian, but I don’t know if it is the necrophage who build it. Moreover, the unknown faction who use to be as powerful as the necrophage is now the first faction in the game, and I need to get bigger quickly if I want to be able to overcome him.





Sorry for the bad English.

Khorne cares not for your prayers. He cares only for the blood, no matter whose.



Joking aside, I'm sure a lot of players would be willing to give you advice. If you could provide some screenshots and some information about the technology and resources available to you, the advice would probably be of even higher quality.

to be honest i would say you have no chance of winning an offensive war.

But you could outlast the necrophages if you play to your strong points as vaulter and keep teleporting your armies around and defending as good as you can while keeping your science up.

then with your higher science you could outfight their armies.

here is my tech tree (I am the most technologicaly advanced faction)
