I have noticed quite a few luck gear with 4% DCI and 150 luck. I took a stab at just making 150 luck with copper runics (4 charges, with "of Fortune"). It took me about 5 hammers just to make one clean 150 luck piece. I can't imagine how many I would have to burn to get BOTH 4% DCI and 150 luck...I'm guessing there is an easier way. I could switch the 4 charges for DCI but then I get a ton of 5% DCI items.
