So I can stop replying to PM's, and because I hate all the guys here who taunt that they have a working exploit but don't share it... Enjoy, and yes this DOES work. Done it for multiple accounts already...
Yes, offline still works. Done it for me and 2 friends already and still have the otto stone. Does NOT work on box itself though, just stone. And... best to test with a crappy silver exp roll stone first though, as the trick only works SOME times. Other times, it eats your stone, even though it was done exact same way. So, I test with silver roll like 3 times to make sure it's working, then use otto stone.
1) Open inventory and shared bank. Have exp stone in inventory.
2) disconnect from internet
3) pass stone to shared bank
4) use stone
5) reconnect
Cross fingers and hope bug works. Best of luck and enjoy, and definitely make sure bug works before eating an otto
Thanks goes to that guy who originally uploaded this exploit. I just went and tried it with otto to see if it still worked
Didn't come up with original exploit though.
