The duck tape passes any effect that is placed on it on the first tiles above, below, to the left, and to the right, but not crosswise. Example 1: If an emerald were to effect the duck tape, if a weapon was beside the duck tape, even if not above or below the emerald, it would be effected by the emerald. Example 2: If an arrow were to be pointing at the duck tape, empty spaces that would not count toward the arrow's damage, would effect it if it were adjacent. Hope this helps.
