And the hostility thing-... Toady said that, in fortress mode, the vamp has to be found out first. I'm guessing the same goes for adv.
I doubt that. An Adv Mode justice revamp would have been a major undertaking in its own right, and we haven't heard about it.
Toady after reading the latest devlog entry i was wondering if only the blood of intelligent creatures work or if you could suck out a bunny or a boar. Secondly i wonder what would happen if you suck the blood of a creature that has an interaction linked to its blood?
You can attach any properties you want (including interaction-bestowing syndromes) to the blood of any species, and those should be respected regardless of historical figure status. The historical figure limitation applies to material properties that are attached to the blood of only a single individual instead of the blood of the entire species. When a dwarf becomes a vampire, that status is stored
in addition to all of their normal dwarf attributes from the raws, and to become persistent, that individual status has to be attached to a historical figure.
If you made a whole race of vampires, then the blood syndrome would be part of the creature definition, and the hist fig info wouldn't be necessary to contract the syndrome.

I started the vampire process by adding ingestion syndromes. These'll be used to give the option to make drinking a vampire's blood a way to pass along the curse, but since it looks at item materials and contaminants and so on, when we get to poisoned apples/alchemy/etc./etc. that'll work without any additional fiddling. It should also simplify some modding workarounds (any added food material or liquid material can be given ingestion syndromes).
