I'm finally getting near to getting my Relic to Novus stage (have like 34 alex), and I'm infusing as I go when materia prices are low on the MB.

My question: If I am going to split Det/Crit/Acc on my Bravura, am I going to need any rank IV Materia at all? Meaning, can I reasonably fill out the entire 75 alex with just rank 1, 2 and 3 materia of the 3 types?

Thanks!
