How works Necro Call?

[ArkhanTheBlack]

The level of raised creatures isn't the same but dependent of the dead creatures level. For example all Archer will involve undead Archer. I didn't notice any random there, once you know what type will be raised you can predict what you'll get for a given dead stack.

Yes, in some cases it made sense, like spiders and archers. Is there somewhere a list of what creatures are transfered into which undead?

Book of Evil is worthless for me because of spells like lightning, that's very unpleasant to see your book kill many of your creatures.

Well, I summon them at the start and let their spells off. At the moment the lightning spells from the books are more powerfull than my own damage spells. If the enemy gets too close, I can still use them as 'fight books'. A level 3 book is quite powerfull although they get problems with real killer stacks. However, if they cast some nonesense at the start in important battles, it can be really annoying. Otherwise, they can easily win battles for me with minmal or even no losses. The power of the book depends extremely on the intelligence of the hero.
