Please note that the succuess rate/profit of this will depend on your server economy.
Using this method you could easily move gold from one server to another. This works with any server or faction regardless what level you are, the only requirement is that the characters are on the same battle.net account.
This is extremly simple, all you need to do is:
- Browse the Auction House on Server A for rare and/or high level Battle Pets.
- Buy the pet and learn it.
- Log on to Server B.
- Put the pet you previously purchased on Server A in a cage on a character on server B (Right click it in Pet Journal).
- Sell the caged pet on Server B.
TCG Pets are great for this as they often go for 200k+ gold
Some of the rarer and more expensive ones are:
Spectral Tiger Cub
Soul-Trader Beacon
Rocket Chicken
This has enourmous potential but selling the pet can take a while depending on what server you are on. I sugguest you check the servers economy before moving the pet and maybe even trying to find a buyer before moving it.
If you want to learn what items are going for on your server https://theunderminejournal.com/ is a great site.
I hope you enjoy this guide/tip.
