Took me 17 tries to get a x2 int hat. Took me one try to get a double meld on my legs. About 4 tries to double meld magic acc on my electrum scepter. Problem is you don't know if they were stupid and made moon/day/color socks affect meld rates. After HQ'ing some mahogany pattens of int and seeing a 22% chance of success for double melding two +12 hell's fist I'm pretty much only melding HQ gear now.
