Ok today I got a quest called Umbrafen Eel Fillets http://www.thottbot.com/?qu=9780 and I started doing the quest and realized the drop rate sucked so I abandoned the quest and went back to town and I noticed there were a couple more quests there I hadn't got and one of them was this quest so I accepted them all no realizing I got this quest again and I looked in my inventory and noticed I had gotten another Potion of Underwater Breathing so I figured I would just never do this quest and any time in the future if I ever needed to do a underwater quest I could just come and start this quest and get a potion : )
PS This also works well with my other guide http://www.mmowned.com/forums/wow-gu...ge-1-hour.html
