I dont know if this has been posted before but here goes... You have to be a hunter to get control of a wyvern by sending pet to attack then fly while you have a wyvern in control you can go into the water and not have breath and fatigue so u can go pretty far out you may disconnect. If you get the quest http://thottbot.com/?qu=3602 he gives you a box and it has http://thottbot.com/?i=17973 just use it and abandon delete the other things if u want just use the orbs till u get much felhounds as you want they follow you for 30 mintues they dont fight for u its just fun having them around..
This is my first post hope u like itYea and you can do eye of the beast and control your pet and go swim you wont have breath i dont know bout fatigue you can recast eye of the beast again and again.
