actually uber d can only drop an anni charm....atma is wrong on this oneDacar92 said:According to the ATMA drop calculator, Uber Diablo has the best chance to drop it, at 0.007729% chance to drop. Diablo, baal and Meph can also drop it and their first kill being the best chance. Try the Pit in hell, too.
Even though ATMA is a single player utility, the drop calculator can be used for Bnet play as well. Get it here
