I thought the main reason vampirism doesn't spread is that the victim is typically killed by blood drain. The megabeast vampires in Dark Ages specifically have bite interactions, as do all the animal forms.



I figured that might have been the case, though you can drink from someone in adventurer mode fooorrreeeevvvveeerrrrrr, which makes you wonder why fort mode vamps are so dumb and always leave drained corpses laying around... but I guess it's a sorta control method to alert you to the presence.I've tried several times to do things like bite the hell out of someone, going so far as to have their guts hanging in my inventory by the time I leave (a kinda trophy habit I started because it amuses me that nobody mentions the length of intenstines hanging out of my mouth, like being on a date with brocolli in your teeth, except way more horrific) but deliberately leave and travel away before they die. I figure if anything would transfer it, being disemboweled by someone's teeth after having them gnawing away at various bits of unprotected skin would have... but it doesn't even show up in legends mode despite having seen a couple of times where someone was injured by a vamp but got away.
