What you will need the item...[Rattlecage] and [Tal Rasha's Armor]
NOTICE - The two plate body's look exactly the same!
OK now either create a game or join a game that involves trading Tal Armor.
After that,
1) Locate your victim and place out Tal Rasha's Armor.
2) After a while of negotiating you most likely will say you will charge 1 HR for the item.
3) While the other person is looking through there inventory, switch the two armors.
4) Hopefully, they will place out a High Rune and accept the trade.
NOTE: This doesn't work all the time because a lot of people aren't total idiots. But, I get this scam to work about 2/10 times I try!
Good luck and happy Diablo II! Scamming.
