Yes, I don't think they're altering the spell fragments. Saying that, the Spire should give you all the fragments you need. When you do the Spire plus have 10 moonstone libraries, you end up with 1.4 million fragments.[Edit, addition] Also if the production changes from scrolls to silk or crystals, would we still get the spell fragments as the additional boost? Those are even more helpful than the extra scrolls for those of us smaller, newer players without the ability to top the spire every week.
