I need to kill Hurricane Wyverns in Ifrit's Cauldron for a Wyvern Skull for my Opo-Opo Crown.

We would have to pass one to do ZM5 fire, which I think people still need.
I'd really appreciate it, and as of right now, it isn't a huge deal, but might be shortly.

Thank you everyone.

Here's the quest for everyone...

Once you have received the scent from Even More Gullible's Travels, speak with Lulupp the Opo-opo on the airship dock (G-7), where you will be introduced to Vuih Stecoppah in the cutscene.
You must trade the following items to the corresponding Opo-opos in the correct order: {Failure to trade in correct order will result in the loss of all previously traded items, and you must start from the beginning}
1. Lulupp (G-7) on lower dock, near Dheo Nbolo.
Broken Mithran Rod: Mithran Fishing Rod can be broken by fishing or bought from {{AH|Weapons|Ammo & Misc.|Fishing Gear}}.
You can break a Mithran Fishing Rod fishing up logs with a Fly Lure in East Ronfaure's Cheval River (fishing skill is required to be high enough to at least drain the fatigue of the log, otherwise your line will snap and you will loose your lure) or in Kazham (with low lvl fishing skill + terrible feeling + monster music) or (Something caught the hook!!!
