Novus weapon upgrade system findings

[Nekodar]

Since I didn't see this covered in this thread, for materia infusion purposes the Omnilex (And presumably the Thyrus) count as already having 9 grade 1 materia infused in the scroll. So you infuse 2 grade 1 heaven's eye materia before it moves to needing grade 2, but you do need 11 grade 2, 11 grade 3 and 11 grade 4 materia to complete capping out the stat.

While interesting, I'm confused as to why anyone would want to add accuracy over the other stats onto Omnilex and Thyrus.
Personally I'm currently going for max tier 3 materia det/pie/spell speed for my Thyrus.
