I won't bite you, but there are a few spawns I can point you to. You have to wait for it to come back though, you need to be in the new moon cycle. I know that the Werewolf and Vamp spawns are 1.5 real days... I forget the number of days between them.
You REALLY need to make sure you want to be a vampire. There is a huge amount of fire damage, spell and physical in the game. If you do not feed by sneaking up on living, human victims and feeding on them, your disease progresses. You will always have 50% increase damage from fire. Your health regen takes a hit too, up to 75% negative. Since it is now part of you and is treated like a racial trait, those negatives are pre mitigation/modification. So you cant just pop on the templar health regen ability, and it makes it all ok.... That is not how it works. It is hard sometimes being a vampire.
Just some food for thought. It is an all the time thing, day and night, fire hurts, health regens slowly, the abilities are situational at best. You need to stack stamina for blocking and rolling out of attacks. You also have to be Johnny on the spot with not stepping in the stupid. So if you think you can handle the extra work and are competent enough to play it, then let me know I will tell you where to go. If you are going to whine about constantly dying and forum rage post about how *enter favorite word* the vamps are... let me know so I can tell you where to go....
