If i have read correctly.
The first possibility is the correct outcome when using the scroll.
Taking a 1 star equipment as an example when scrolling with the mentioned scroll which you possess.
If the scroll passes, the equipment will be upgraded only to the third star and not an increment of three stars which would total to four.
In addition, the scroll will not work if the equipment has already been scrolled thrice or more.
