Is there an efficient way to get a large number of Twilight Crystals in KHIIFM? I know that only the Sorcerer Nobodies drop them, but the problem is that they're very scarce; only 2 of them spawn in the entire Castle That Never Was in the Naught's Approach room. I have all Lucky Lucky's possible equipped to Sora, Donald and Goofy. Any suggestions?
Peace!
