Should I buy a maple pyrope staff?

well that depends on what the Ma is for the pyrope staff, and if you are willing and capable of scrolling it to a better stats? Otherwise, i would suggest sticking with the current staff. Another alternative is that you can get a scrolled pyrope staff, which i would highly recommend, but it is definitely going to cost a bomb. MA 91 is considered not bad, for a not-funded mage.
