Wow Retail, Gold/XP Dupe (Gamebreaking) (Patreon)

The following exploit is likely to be of limited duration before a fix and requires a two-man to operate and/or a second account. Multi-boxing software is not essential but may be helpful. 

North of Paw'Don village in the Jade Forest is a location called "The Shrine Of Remembrance". On the map this is the area between D and o in Paw'Don.

At this location is a treasure which awards experience and 10-11 gold. 

If you group up with a level appropriate player they can loot the treasure infinitely and gain xp by repeatedly starting and dropping party sync.

EDIT: Khser has discovered this works with a level 1 (see below). I tested this with a starter edition account (starter accounts are free) and this works also-this means you only need one paid account and do NOT need a partner.
