Novus weapon upgrade system findings

[Nekodar]

Hm, was just wondering... wouldn´t it be A) better and B) cheaper if you don´t max out 2 stats than distribute for 3-4 Stats

For my Thyrus Novus I'm planning a det, pie, ss distribution such that I don't have to use any tier IV materia at all.
It's entirely up to you what stats and which distribution of those stats you want to put on your weapon, as long as you fully infuse the scroll.
You can put on crit, ss and acc onto stardust rod if you want to (assumption based on listed class here) and would likely save gil that way.

You could of course make your stardust rod useless by putting parry+skill speed on it instead
