My fav way to gather bc3s is to run snowcloak as a goldsmith assuming u get evrey drop from it there are about 4 items evrey run u can break down u also have to count the green gloves and helm can be exchanged for gold smith food so out of all possable drops as a goldsmith u can break down all but 3 pretty good chances each one is a 20% chance to gain 1-2 bc3s and also they break down into rose gold ingots now the awesome side of those is that you arnt done with the item till it breaks down into a rose gold nugget u just keep making rose gold brackets for 1 rose gold nugget till u get a bc3 u finally fail when u hit rose gold nugget now the only problem with that is all the people who need on items just bc they want to but I have found latly letting people know y your there has led to a bigger outcome people are rather nice about it actually
