Empty Head, I was going for, since they're Ghosts, which don't really have much of a head, thereby being empty head? OR maybe just a lack of emotion, sicne empty head prevents things like attraction, confusion (how do you confuse a ghost anyway?). etc...hehe~ -sweatdrop again-

And Night vision because Dusclops are ghosts, which are native to the night, so it seemed fitting. As for Duskull, It has a fire behind it's 'eyes', so I figured that would work for him as well

Other than maybe Eclipse or Confound, None of the other Topaz abilities appear to flow with Dusclops' style, imho.
