Thanks for your answers.
1)I don't know honestly, Arcanes are fantastic at crowd control, you've spells helping the team and helping controlling the sorts of the battle.
Divines help with heal and buffs for the whole party, that's the general idea i made so far.
Well i agree. For me the best way to be a necromancer is to get few but strong creatures (this is easier to manage and doesn't get your party hating you because of dice rolling and long times actions, and it's cool aswell to have a big powerful monster instead of 1000 weak skeletons.
2)Depending on a deity's favor is a problem? I don't get it ^m^
3)So, how to become an undead?
4)So you're limited on some templates only?
5)Clear as water is.
