Had to create an account here just to tell this story.
Wanted this spear bad fer DRG, so me (59DRG/SAM) and a friend (60PLD/DNC) started hunting it.
First time through the Mythril door he was up, so we re-raised and tried him somewhat unprepared just to feel him out, and he brought a link with him, and we died. Re-raised/rested and a 75 DRG walked by and offered to help us kill it, so we do and HE DROPS!.....so I cast lot.....fer 20pts and thought whatever b/c everyone is passing.....until my friend accidently hits up on his controller and lots it fer 625, thus taking it on me. He though it was no biggie and he could just trade it to me...until he realized it was rare/ex...so he has a shiny new Calamar for himself.
Needless to say he felt like crap for it and decided he wasnt leaving the area until we got it again, so we hunker down and start killing everything around Pahh's pop point. So we finally get it again after about 2hrs and this time a 75 THF with TH3 happened by to help us so we figured it was likely to definite drop......no drop.
We call it a day, get back on day after go at it again. Pop him and kill him ourselves using 2 hrs, no drop......4th pop and 2 ppl swoop in and take him on us but invite me fer drop.....no drop............1 more pop last night after 3 hrs of killing PH's and again no drop.
So far we are 1/5 and now its almost not worth having the spear anymore with Dark Mezraq available at 60....but I still want it out of spite now lol.
Anyway FYI it seems to be anywhere from a 1-4 hr pop time if you keep killing all the Hags around the 3 little rooms just past the mythril door. It does Spinning fin a fair bit which stuns decently to lvl 60ish .
