How can I beat the Ermor?

[shovah]

SC's with good stats, reinvig and regen can tak most ermorian troops. Try some thugs/SC's with support from massed priests, smiths with earth boots casting summon earthpower then bladewind and maybe some thugish knights (they have high prot so undead cant really hurt them, give them charcoal shield, amulet of reinvig and ring of regen and watch undead fall). If you can summon golems get them, they can use good buffs, have full slots and are strong. Also try a bunch of black knights with legions of steel/army of gold or some other form of buff.

Get full Dominion and build lots of temples. LOTS of temples.

[shovah]

yes, if his dominion reaches you lands your in trouble.

Your enemies will never fatigue, so they will eventually beat your living soldiers, no matter how superior their stats... unless... you cast Relief!

For invading Ermor, bring Endless Bags of Wine. Herald Lances and Flambeaus are nice, just for their spells, not for combat. Troopwise, favor archers over melee, but bring enough melee units to protect everyone (heaviest armor + shield; attack and damage don't matter, only protection, defense, and morale). The best offensive mages are Fire (Holy Pyre, Falling Fires), Earth (Blade Wind), and Death (Dust to Dust, Wither Bones). The best support mages are Nature (Relief - essential!, and optionally Mass Protection), Air (Wind Guide - increases precision of mages and priests, not just archers!), and Water (Mass Quickness for 2X priest banishment).

Lastly, give your Prophet (or highest-holy priest) Boots of Quickness, Rune Smasher, Lucky Coin, Amulet of Penetration, Girdle of Might or Amulet of Resilience, and have him cast Banishment along with the other priests. As was said, you need lots of priests. Think ~40 priests with 50 archers and 50 heavy infantry, all backed by a few mages, to deal with armies of 1000 undead without significant losses. You need live soldiers and mages because the AI always mixes living (starving) units with its undead hordes. Ideally, your losses will only be from province defense (30+ at a single-province chokepoint, or ~20 otherwise) when you are the defender. Wars against Ermor require more PD than normal.

Note that if you know ahead of time your opponent is Ashen/Soulgate Ermor, taking a Water-9 pretender is a good idea, just for the extra banishment.

P.S. Don't forget Fanaticism / Sermon of Courage! If your infantry run away, you lose 2000 gold of priests.

[Fate]

A neat trick, especially against the AI, is to send some scouts through there territory and attack 0 PD provinces. If there is no leader, they will all fall apart.

[Folket]

Intresting, but from what I have seen the AI builds pd everywhere.

Assassins can work wonders. Eliminate the characters holding the armies together before you attack and Eremor becomes a non-issue, as long as you can keep his domain away.
