This is a question about Tone:
Does Blood Borg support making players feel powerful at all given the predatory nature of being a vampire?
Or are the PCs pretty much just destined to die or otherwise live hopeless existences like in Mork Borg?
I’d say it’s little of both. The vamps survive at zero hp unless there’s sunlight or silver involve and they die forever.
however, their hopeless existence is societal: the upper class hates you and you are relegated to lives in alleys and sewers. You will never be at the top, but that shouldn’t stop you from having a good time.
