What are the best units to turn into Prophets?

is there any point in h4? if im not mistaken there's only a spell that paralyzes one unit each casting.

For nations that use a lot of undead (Ermor, C'tis, etc...) they have national priest 4 spells that are "entire battlefield" spells which increase the attack of all undead units. That is one very, very good reason. There might be other nations that have level 4 priest spells...

Also put a level 4 priest with a temple and turn on the preaching and you'll see the domain shoot up (it won't fail it's domain spread check).

I'll always try to prophetize a level 3 priest if it can be done without screwing up my first few turns too badly.
