My gaming group usually plays dnd but we are going to play a world of darkness campaign but im a little confused so here are my noob questions about world of darkness
- Can we use different books such as hunter, vampire and promethian in one campaign?
- Can I have a character who is both a promethian and a hunter?
- Would you suggest using multiple books in one character?
- What happens when i get a big sucsess(5 or more i forget the real term) on a attack?
Different books are fine. You may find some oddities in interactions of powers, but nothing too bad. Hunters can often be more focused and less overall "powerful" so watch that as well. "Balancing" encounters may be tough, but is what it is in WoD games.
Hunters should NOT be any supernatural. Risking Willpower, Tactics, etc. are really what makes a Hunter a Hunter and thus more or less a "major template." This is not a hard rule, as far as I know, but a "strong suggestion" at least. Balance would be even harder if you have a Promethean who can Risk Willpower. Tactics make sense for Werewolf packs to me, but you need to redesign the specifics because many Hunter tactics just don't make sense for Werewolves to use.
Multiple books one character...depends. Hunter characters MIGHT jive well with the psionics in Second Sight, but that's about it. I'd definitely say that you should stick to "one game line" per character. In short, if you're playing a Vampire, you can only get stuff from WoD Core + Vampire books. If you're a Hunter, WoD Core + Hunter (and MAYBE Second Sight...maybe).
Exceptional Success on an attack is just more damage. Usually, that's more than enough! The Combat Hacks in WoD Armory Reloaded might have other ideas, but I don't recall. You could say that dealing 5 damage in one attack is a blow that cripples a limb or something, but really, the damage is its own effect.
