Ok /tg/, let's recap:
Every vampire is very weakened by sunlight, hurt by holy items/magic and are undead. Blood is something every vampire needs, but they won't die from not having it, they will just become more and more like a corpse. Vampirism is adquired how? Mental faculties stay the same, meaning that they will slowly become insane by their thirst or the horrors they commit. Normal vampire powers (super strength, super speed, super agility)?
Shadow vampires are a extremely rare caster-like breed of bloodsuckers who hide in the shadows and are eerily able to shield themselves (albeit for a short time) from the sun, or to shroud in darkness a zone at night (i.e. shut down any artificial light like torches, lamps, etc.)
Chinese-like OCD vampires who have a very tight society affected by normal superstitions because they believe on them, rather than being physically weak to them. I think they show be mobster-like and have one cabal of them in each city, maybe with diferent cultures.
Skin-wearing sick fuckos who are just like serial killers, only with a reason to kill...and vampire powers. Immune to sunlight damage while wearing a skin,and it requieres a very difficult Spot check to even slightly suspect that somebody is wearing your buddy skin, but it rots within few days. These guys should look really fucking scary without a skin, something on the lines of skinless ghouls with protuding fangs.
Don Juan De Ceased style vampires, stylish, charming, smart and narcisistic mother fuckers who drink blood every night to stay lucid and beautiful. Even thought someone may think otherwise, they tend to be nomad and use the "new hot guy in town" image rather than stay in one place for long, since whenever they get a date or go to a party, someone dies. They should get bonuses to CHA, Diplomacy and Bluff while fully fed, otherwise they start to get penalties on those stats and mentally unstable.
Am I doin' it right?
