I see that you got inspired by my idea of a vampire lol.
Use undead talent and set the poison resitance for the "race" to -100. This may set the poison resistance to 100
Hey Martius. Great minds, right?
The thing about using the Undead talent, and setting poison resistance negative, is that it doesn't work. The Undead talent forces your poison resistance to 200%, regardless of negative influences.
With that said, I just did some tests and it seems I can apply a decaying touch status effect that causes healing to damage you, which is great. So now you're immune to poison, but you only heal from blood surfaces and drinking blood.
Healing from poison may fit in terms of vampires being undead, but I like simply negating poison and requiring the player to use blood or coffins to heal, as that changes the gameplay in a significant way.
My plans right now are implementing a "blood pool", which is basically an invisible bar you fill up by drinking blood. You'll be able to store blood in bottles as a quick way to heal/feed, and you can sacrifice the blood you've drank directly to trigger immediate regeneration (sort of a self-heal spell).
