Novus weapon upgrade system findings

It's a more reasonable assumption than going nuts over materia IV prices going to skyrocket.

You're also assuming that Alexandrite use is based on per Materia and not per Stat on the Materia i.e. it could be that you need 4 Alexandrite for a materia that has DET +4 and 10 Alexandrite for a materia that has DET +10. Speculation at this point regardless since we don't know the exact details.
