Xbox One player here, obviously just started on the 9th.

Google seems to offer no agreed-upon conclusion as to when vampires spawn so I would appreciate answers to the following:
-Does the moon cycle actually affect bloodfiend/werewolf spawns?
-If bloodfiends do spawn on a given night, will they spawn all throughout the night? Or only once in that night? Or something else?
-Where exactly are the spawn points? I'm in EP and am aware that they spawn in the Rift, maps seem to point towards the south side of the zone, is this right?

I'm not looking for someone to bite me, I want to find the bloodfiends myself
