So this allows you to fly over island regardless of class/spec/etc. Don't ask me how programmers were drunk in blizz to mess it up but to do it you need to obtain evermaw's item - Mist-Filled Spirit Lantern - Item - World of Warcraft
After you will get it just get in sea (for example good spot is around ship - 26 27) mount up on flying mount & the most imporant thing get crossrealm friend to inv you. When he will then I advice you to target any mob (kind of timing thing) & when mob will start to vanish (due CR invitation) then you start flying. Result ? flying even after you die, blazing chest for free, fast rare checking etc
Edited:
Tbh after some time I think it's kind of useless because even farming eggs wouldn't provide you as much coins as you'd aoe them in groups
