Mid/late game defense against undead??

[Saxon]

With the huge crowds of undead you face, accuracy is not very important, but you still may wish to consider getting the Big Blue Eye which raises accuracy and giving it to some priests. This will ensure hits almost every turn, increasing their effectiveness.

As a nice bonus, they will rack up huge numbers of kills, leading to hall of fame entries. If you get the precision improvement on one of them, you have a priest who never misses and can pound those Last couple of undead commanders at the end of the battle.

I know it does not sound that exciting, but buying as many of the 50 gold priests as you can for a couple of turns in every temple you own will quickly generate a force that eats Ermor, as run by the AI. Have priest in each costal province and you will slow down any surprise invasion. Ermor relies on numbers and the priests take that away.
