please tell me if this is a repost and link me to that thread; I couldn't find anything with both search option and page browsing.
This exploit is Horde only, as far is I know.
During the Pandaren campaign quests:
"Clearing a Path" and
"Legacy of the Korune" (which follow after picking up
"To the Valley!" from general nazgrim at Domination Point).
You'll get two helpers/battle companions called "
Ranger Orestes" and "
Aenea".
You can make unlimited copy's of these NPC's by zone-ing in 'n out of the Valley of the Emperors and Kun-lai summit.
I use to do this around the stone gate found at around coördinates: 58, 48.
If you cross the border very fast, multiple times, in 3 seconds and then wait in the Valley, then the NPC's will spawn one after another for unlimited time and amounts.
What you can do with it? About 750K DPS on Sha of Anger and make your daily's alot easier... and have fun with annoying alliance hounds.
This exploit looks and works alot like one we know of in Townlong Steppes, where you get a Pandaren companion, but that one got fixed I believe.
