As of 5/8/24 on Teek server.
I started by just sitting at the giants and waiting for a mob to come up and stand there. There are some mobs that come kind of close that I ignored, but killed the one that came very close like he was going to run straight into the middle of the giants. There were only 3 people in the zone so I could pretty much see what spawned after that, thought not with 100% certainty.
A mob ended up spawning somewhere around 2650, -1350, and that is where I ended up sitting to kill whatever popped. Did this for 10-20min and Kwinn popped right in front of me. Killed him and then stayed for a bit to see if it would happen again. Just kept killing any mobs that came to that spot or spawned there. After about another 20min Kwinn spawned again, but to the southeast around 1930, -1670. He then walked to the southeast point in nikokirei's post. Note that the first spawn point was close to his northwest point, but not exactly.
I did follow what I was pretty sure was the PH and he walked in a north/south zig zag pattern very close to, but not exaclty on, the locations in nikokirei's post. Pretty much all the other mobs would spawn and start walking directly south or directly east/west. Drolvog Scavenger and Froglok Nok Shaman are 100% in the spawn table, can't say for certain on others.
If I have to do this again I'll probably just go with the giant fort tactic again as there seems to be only 1 or maybe 2 spawn cycles that walk to that point, and 1 or both of them are in the kwinn cycle. Never saw a mob actually spawn there though, they spawn down by the hill then path there.
