He had started off at around 100 Tol'vir solves. At around 300 Tol'vir solves he crafted Zin'rokh, Destroyer of Worlds. That was his last rare solve for Kalimdor, except the Scimitar. Prynne was left with a lot of hope that he would get his perfect sword soon after.
I'm pretty sure the moral of the story is to not give up hope on getting that one perfect mog piece, even if it takes a lot more patience than you have! It makes all the difference though ^.^
