when exactly dose one perm their runes?
i understand it has somthing 2 do wif flaching the item in the trade window... but wot if ur the only one in the game?

ok if ur referring to the trade method this is how it works. when u enter a game your duped runes immediatly become flagged by the server, this will let the server know that since their duped, once u exit, they will be gone. now to temp perm them this is what u do.
1. bring a friend into the game, open the trade window and close it immediatly. exit the game right after u close the window and u will be fine. this is because when u are in a trade and u reject it by pressing escape, the server rolls back and the flags on your items are removed.
2. a 2nd method u can do to perm runes is to get like 2 duped runes (like duped mals) get a saphire, and upgrade them. this perms them

Upgrading does not perm them. This can be traced, I'm 100% sure, I read a big thing at blizzhackers. Go to act 5 lazurus(I forgot why him) and sell your runes to him, make sure you have 300k for each rune, then buy them back, I'm not sure if this works 100% but I think it does.

can u show me the link to this discussion on bh, because in pretty sure if u sell runes and buy them back their id tag remains the same
