How works Necro Call?

[Vilk]

I just got the evil book spell so I'll be able try a bit around it. In term of damage there are 4 types, physical, poison, fire and magic. So it's possible that the book is immune only to spells that aren't fire. The point here is not be able to cast spell on them like for black dragon.

I tried quickly the evil book, in a gremlin fight, but a quite tough one because it's the upgrade to archmage staff. I cast two level 3 books and first point I remember that you didn't choose the target but in fact you do, weird I don't remember that.

One of the two books get killed in one hit. The second didn't get attacked and did a poor lightning spell that does ridiculous damages. Well my int was 16 only. Enemy was too much spread through the board that didn't help make efficient the lightning not to mention the very low efficiency against troops with magic protection.

Overall that's roughly what I was worry about. For now I'll save crystals and won't learn the spell but I'll do more attempt in different fights.
