This mod does look quite fun. I only have one problem that I couldn't find a solution for. Is it possible to disable the vampire mob giving Sanguinare potion effect? So that only items can give you the effect?

EDIT: The configs are lacking an option to disable vampires capable of infecting the player with Sanguinare Vampiris. When a vampire mob feeds or hits a player there is always a chance for infection. But in packs that use progression, being able to turn this setting off and use an item instead to infect would be a blessing. Otherwise the only option I see is to disable the spawning of the vampire mob outright.
