Gold, Points or amount of charms or amount cheese. (Not SB|+ because it's premium)
I've tried 4b*1, 4b*8, 4b*1+6 and "all values" for 'Gold', but so far only 4b*1 works. Every once in a while (A few times a minute) the address refreshes and changing it does nothing.
My methods of finding the addresses: Search 4b*1, then buy something, search again, sell the same thing, search again. Down to one address, but it keeps refreshing. Suggestions?
Also, if unlimited horn sounds could be found (Though not likely, as it is run online through the m.h. server, I think)
