It cant be a red staff (tbh im not sure how it turns red but if it turns red its junk, maybe dont cube it until ready to insert? not sure).
As I recall:
Quest item from Normal or Nightmare difficulty
cannot* be used to complete the corresponding quest on a
higher difficulty setting; the
item text display turns
red as is the case with this
Scroll of Resistance.
Quest item from Nightmare or Hell difficulty can be used to complete the corresponding quest (if not completed) on a lower difficulty setting.
*) An exception is the
Horadric Cube, which can be used regardless of where it was originally found.
