+1 Necrosis is a center spawn with 2 scarbs on either side. Both the PC live and Al'Kabor were both in this manner. Best,
This is also my experience. Only other server I played on was PEQ and if I recall that spawn was weird so it might cloud people's memory of that camp. PEQ I remember any of the 3 spots would spawn it, but never saw 3 at once. No idea about p99. AK and live was always 1 in center for me.
I don't think it should be possible for more than one to be up, had never seen it before the other day.
According to http://eq.magelo.com/npc/98295, it can spawn in those 3 places. not sure about the one up ahead. I can always make it so only 1 can spawn at any given time.
I went ahead and split up the spawns. The center one will always have a higher chance to spawn than the other two so it should be very very rare if 3 ever spawn at once.
A quick look at some of the other named in Magelo suggests it's not to be trusted on spawn locations: three spawn points listed for Gruplinort, ten for Emperor Chottal, forty-three for the froglok ostiary. Still, this seems like a good compromise.
