I completed the collection at Timerys, and so FYI: below are the kill counts I had when the DPK was satisfied. There may have been others on this map before me, and there might have been 1 or 2 people exploring during the same day, so these are just ballpark estimates.
Yellow Pag Clamper - 500
Blue Pag Doper - 250
Yellow Pag Shearer - 400
Green Pag Nurse - 650
The Nurse’s pikestaff was the last to drop. Have fun!
