Wow... thank-you RNG.

So instead of maxing out 2 stats, you can choose to stop after Tier 3 on your 2 main stats and use a different stat to finish off the Novus.

For instance, say you're a BLM that wants to put Crit&Det on their novus, but don't want to break the bank using Tier IV materia. You can put 33 crit & 25 det on your novus, and then add 17 spell speed to finish off your novus. In this way you're skipping the use of 11 Crit IV and 8 Det IV (actually, it will very likely be more than that ... see the OP) and instead use 11 spell speed I and 6 spell speed II, which is millions of GIL cheaper. It's a perfectly legitimate question to ask how many millions you are willing to spend to get that last 17 stat points instead of using a cheaper option that's almost as good.

Only intend to max SS@44, which require 11 pieces of tier IV.
with possibility of failed infusion... farming gil doesn't seems worth it.
