Tactic : how to fight undead ?

[Esben Mose Hansen]

In any case, priests are the key. Each army should contain many, many priest. build as many as you can. Then set them on banishx5.

This is why the AI does so badly against Ermor. Not enough priest.

[Unknown_Enemy]

Bring on a Priest factory and just crank out score of Priests to banish a swarm of undead...

Of course....feeling stupid.....

If you're up against Ashen Ermor, with skeletons and ghouls and whatnot, then missile weapons are also pretty effective, since most of their troops move slowly and their only ranged attacks are javelins.

If it is Soul Gate Ermor you are fighting this won't be nearly as effective since the arrows will have a hard time damaging their ethereal troops. But any sort of area effect damage spell should be useful, like say Holy Pyre, or perhaps Blade Wind.

But of course you'll want lots and lots of priests no matter what.

People have already mentioned buying Priests. Treat Priests as elite units. They cost less than most single cavalry units. Have a minumum of 10 per army. They are also great for driving down Ermor dominion, which determines how many units Ermor gets.

Your main goal should be to keep your priests alive and banishing for as long as possible. Get some meat shields in front of them. Summoned mindless units are perfect (vinemen, vine orges, Mechanical Men, your own undead, etc.). Heavy in fantry works well too. Your biggest worry for your meat shields is that they will rout.

Get a bunch of archers too. I prefer archers over crossbowmen versus Ermor, since penetrating hogh protection armor is not the main problem. Massed archers even work versus Soul Gate, since ethereal units have very low protection, and 25% of missles get through the ethereal.
