If you're doing this to grind for your Epic 2.0, you're going to get tired very easily. Here's some help to make it go quicker...
Once you pick up the quest, immediately use the Jin'tu's Gift to get to the Hua Mein village.
Do the arena then fly to Toxxulia and kill the 10 creatures.
(Fly over to Kerra isle and pick up the quest)
If you're doing this on repeat, see step 6 substep on how to avoid this extra trip
Fast travel out and then back into Sundered Frontier, to the Druid Rings
Find the spirit
Fly back up to Kerra isle
If repeating, you should take the quest again BEFORE accepting the quest reward. This will allow you to avoid step 3 next time.
If you're a fast zoner, you may find it quicker to quick travel out and back into the spire and fly from there, especially if the previous step sent you quite far South West
Evac. If you don't have evac, Fast travel out and back into the spire, take the portal to Paineel and hand in.
