Hi Guys!!! i have seen this video befor you post it here so i know the truth :P ! I tell you the story .....
This guy is BD and he died in a pvp and he took de-lvl so his friend bishop resurected him and he took the xp back so he took the lvl again,
when his frind resurected him in the same time he changed his dual churugi in demon staff+10 .
So as the server was bugged whenever he changed his dual churugi to the staff he took lvl up !!!
It dosen't work in any server i have ever played :cry:
