There will be little to no combat, unless of course you provoke it. So, prefer an "intellectual" approach to your characters. You can be any clan you want, except Baali (Storyteller's Handbook) and Lhiannan (Storyteller's Companion) due to their roleplaying difficulties.
Well, that halved the amount of characters I could play.
Fortunetly, this also means I have a whole half left
Gangrel,
Nosferatu and Assamite went out of the window.
Cappadosians and Tzimisce was never an option.
Salubri..not really. I don't fancy being hunted to extinction.
Other ones not mentioned:
Not familiar enough to play, have no interest.
...actually, I can't ever say no to the possibility of playing a Nosferatu.
So that's not out of the question yet.
Either Malkavian, Lasombra, Ventrue, Brujah or Toreador. Perhaps even Tremere, if I feel daring.
My username and picture might give an inclination to what clan I owe my biggest allegiance
Gah, so many disciplines to choose
Something I think you'll agree upon based on the restrictions you have set:
Multiple personalities do not have different sheets.
MP have the fun little text that the different personalities can belive themselves to be of a different clan and even have different skills and disciplines, but it all comes down to the Storyteller.
Whilst I would allow this shennanigans with disciplines in some cases, this does not seem to be one of them.
At least not for Attributes and Disciplines, perhaps some variation in skills?
I take it we're using the normal rules for Character Creation found in the book?
What age/generation so to speak, how much more -if any- stuff can we have than the normal vampires constructed by the "point limit" ?
