so i read and heard of people people bumping into vampire nightstalkers etc all i have seen is blooded and masters anyone know locations of any other ones

I've seen volkihar vamps at level 81, not sure about seeing them sooner than that tho

Master Vampires are like Bandit Chiefs, they are generally bosses of an area. The rest are dependant on the level of the player. You will run into the later variations as you level up.

people have mentioned mistwalkers which i though were anothetr from the lore who turn to mist and volk vamps at 50 didnt know if just trolls and more importantly is the vampirism you contract from them betetr then crappy sanguine vampiris
