Well, I tried this tonight in an alliance of 12 people. We killed the wyverns no problem and had two THF's with THII and we only got 1 skull in about an hours work.
After that, the pld died taking a breathe attack that did 1600 damage. Everyone left and the only person to get the wyvern skull was the drg in the party. I think it was a mistake assuming that the drop rate would go so well, it's too good to be true.
If you're planning on getting the wyvern skull, you should plan on staying a while if you're not the lucky type. And if you get people to help you, make sure that they have time on their hands. People agreed to go but only because they wanted the skull too, and apparently they were on their lunch break or something because all ended up saying they had to go when we had pracitcally just gotten there.
Anyway, I'm a 65 BRD and i'm determined not to move another level till I get this crown. I hope you have a better run at it than what I did tonight.
Edit: I was ina rush and don't think I mad eit clear as to what I was referring to. I was referring to the Wyvern Skull drop. Hurricane WYverns in Ifritis Cauldron.
