I'm first going to say the moon phases are complete BS. They spawn indiscriminately on any moonphase. Those guides that say only newmoon for vamps and only fullmoon for wolves im guessing are made by people who don't want people to get it/and limit the population by using fact some fact but not all reverse psychology Idk but moonphase have not effect it's just wait for night and they might spawn.

Second If your going to pay make sure you get the bite(product) first then pay. You must go to the area where the vampirism questline starts if you actually want them to infect you. If they lead you anywhere else or they refuse and or don't know where it is they are scammers. The location is at the top right of the rift at the end of the road towards the mountains on the right.

Third try joining a vampire guild, like mine we prioritze bites for guild members and free of charge(I think it's stupid to charge someone for a gameplay mechanic everyone Fks up on purpose.)

I did find some on the Ps4 the other day so check the bottom, Werewolves spawn in the same area for the top locations I've found in case you have buddies that want that. It's really tidious looking for these things, I've been trying to find it since launch day -_-' yes I have nothing better to do to much time on my hands but anyways.

Me my PSN: Is LEONO__
At the moment I can't bite anyone, for my vampire skill line is at level 2 right now.

You need level 6 to get the perk: Blood Ritual
It comes with a 7 day cooldown (Bethesda Why do you try to limit infectinon rates so much, it's not like there's Dk head players who are vampire hunters and try to limit us... oh yeah there is...
