I just want to know if you can have more than one Death Knight with one account. I read that you can only have one Death Knight per realm but sense there is only one can you have more than one? Me and my brother share an account and we both want our own death knight so i want to know before my character gets to lvl 55 so he can start working on his own. thanks in advance.

He will have to create his own account. One DK per account.

he has to make own account and lvl one char to 55 to make one DK

Ok thanks. I read a forum about an account split could we get that too for my brothers two characters?
