Okay so, I just bought this info from some guy on my server and, considering its simplicity, felt like I was obliged to inform people about it.
All you do:
As a hunter, tame a worm. (Any worm will do, you can't miss.)
Have your worm cast Burrow Attack.
Dismiss the pet in the midst of the attack.
Stable the pet and close the window.
Re-summon the pet and voila you have yourself an earthquake!
Doesn't move or anything, just looks kindof cool. Let me know what you think.
