Most of my vampires live rather normal lifes, so I guess I got alot of "good" vampires, cause they dont really do much if any vampire things, besides drinking plasma packs and teleporting as bat/mist arround the place.
I always give them full sun immunity too.
One of the reasons for this is, that I really like some of the vampire face features (like the dark under the eyes) which are only available to occults (and not even all of em).
But also I just like making occults and have them live normal lifes, idk why....diversity?
I got two "special" vampires tho, one is an undertaker who fears the sun, so he is always cranky during the day...he is also possessed.
The other is a ghoul, my only "vampire" who cant teleport.
What I love about vampires is that their weakness and abilities can be used to make them more diverse, some can eat normal food, others cant, some are eternally sad, some are afraid of daytime and so on.
I dont go by any lore or law, I just do what I like and feel fits the character.
