What the hell is the difference...

Yes and "Scroll" doesn't add the secondary stat. Scroll adds just +3 LUK and nothing else, while Dark Scroll adds +3 LUK and another stat (I forget which). The same situation exists for Bottomwear DEX, there is a Scroll (which gives Dex and Accuracy) and Dark Scroll (which gives Dex and Speed). I hope this cleared up all confusion =].
