First you need a couple Darkmoon "Tigers".
Second you go to the left side of the auctioneers, get close to the boxes right next to the auctioneers, and set down a Darkmoon "tiger".
Now you log out and log back in. (Important, Don't Disconnect you need to LOG OUT.)
When you log back in you should be on the edge of the boxes, DON'T MOVE AT ALL.
Wait for the Cool Down on the Darkmoon "Tiger" to get done and set another one down.
Log out and log back in.
You should be on the boxes...
now just jump towards the auctioneers
