The Hourglass has been changed in the full version of the game to be a much better item, and the ductape effects anything, it essentially extends the range of the item giving the effect, for example, you can put it adjacent to an amethyst and have it effect and extra three spaces, or make a king cleaver able to touch 6 cleavers in stead of 4.
