Aetha

I'm getting a bit testy about the number of graveyards in this expansion that are placed so it is impossible to get to your body. Honestly, what is the point? It wastes a whole lot of my time screwing around looking for a path that doesn't exist, then finally looking it up on wowhead to see if it is yet another that requires me to just take the rez sickness.
If you are going to change the game mechanic then just change it, don't leave it the same in part of the game and break it in other parts. There is no point in rezzing me in a graveyard and telling me I have an option to find my body if there really is no option.

When you accept this quest, you will be granted a temporary waterwalking ability that allows you to take damage and walk on water, unlike the Shaman spell.

In order to defeat Aetha for the Golden Lotus quest, engage her, and continue to move around the outside of the area as she casts Tornado (be careful not to accidentally walk off the waterfall!). Give yourself enough space between the moving tornadoes, and you should easily be able to defeat her, so long as you don't stand in the winds for too long.

As noted in the quest text, this mob is not killable - you "subdue" her, and she runs away.

This NPC makes the cutest sounds when attacked. It's adorable. You'll want to hug it instead of hit it.
