Everyone there is a new scam out...at least to me in act 2 the scam is hard to explain and is very lengthy all i can say as blunt as possible is DO NOT TRADE in act 2
As for as I know, there are about 3 scams in Act 2 when trading the charm annihilus. Either keep it, or kill Uber D. Don't risk getting it taken trying to trade it.
It is by the stairs someone goes into the sewers and comes out when u run to trade
lol, that is pretty old... sum one tried to scam my bro like that (might have been in HC too), but he was hostile with the person in the sewers, so he went in and killed the guy. funny story, but happened like a month or 2 ago.
