i have a ? on it. im a reset and have this item now. my question is i found a perfect icy to raise all its stats up and was wondering can i use this on it first and then raise stats or do i have to use this as last item

You could use it first, though you might want to wait and have a friend colonize it and then you invade back so you can put the uldrinan artifacts and a psy beacon on it. Up to you of course...
