Dealing with Ocean Nations

[Tuidjy]

Pretty much the only way of dealing with 400+ armies is to build supercombatants
that can kill them by themselves. Against the AI, this should not be too hard.
Tell us more about your research, mostly about your summoning and forging
capabilities.

Hmm, yes I was half-thinking that as I am currently researching towards Lamia Queens to get Bane Lords, but to be honest after the last big battle I am not so sure. I have a few Carrion Lords reanimating, but not in any sufficient numbers. Can undead go underwater?? I am new to the game so don't know all the ins and outs and unit capabilities. I have put up Mother Oak and Gift of Health and have Construction 4. I haven't been able to research much as the money has been going towards rebuilding my armies.

Don't worry too much about attacking them in the water. That will come in time. Beat them back off of the land (should not be too hard... Oceania's troops suck on land), and try to find some provinces that can recruit indy amphibians (Shamblers... etc.). In the meantime, empower some mages with water magic (use alchemy to get the water gems if you have to). Ultimately, you should be able to keep them off the land, and eventually have an amphibious army that can attack them.
