[AreaOfEffect]

You'll receive few army advantages over Formoria as they have a lot of the same troops as you do. One good thing is that you can create a lot more glamored units.

Having a pretender with fire will allow for a couple of things. You can eventually utilize flaming arrows with your slingers for one. Heat from Hell in battles with your sacred units (reinvigoration 4 from your bless) is also a combination you will have access to later on. Even still, you have mages that can cast relief, which will allow all your units to survive the nasty battlefield enchantment.

I'm no genius, but as for getting regeneration on you Ri, well they are nature mages. You could just research personal regeneration and skip the ring entirely.

Taking a earth bless with this nation also makes you a reinvigoration machine. Your bless, plus relief, plus all the reinvigoration items your nation can naturally create means you troops and mages can stay strong in extremely long battles. Once it becomes feasible I would do my best to slow battles down to a crawl.

Good luck.
