Any Novus wielders out there?

better yet, how much gil did it ended up costing them?
I had saved 1m for the weapon but I start to think I will need 10 times that amount... crit materia prices through the roof...

1 million definitely won't be enough if you plan to go with BiS. Determination and critical hit rate tier IVs are around 200k (at least on my server) You need 19 and you're bound to get some failures when you fuse too.

200,000 x 19 = 3,800,000

You're going to be dealing with 60% and 50% infusion rates at the end. So 3.8 million would be the minimum. And that's just for the tier IVs. Even the IIIs can be pricey with how many you need.

It's hard to tell if materia prices will increase or decrease as time goes on. Demand for the tier IVs will likely increase as people reach that level of Novus.

Unless you're rich, I really don't recommend going for 31 determination and 44 critical hit rate. 8 determination and 11 critical hit rate is hardly worth 4 million gil. The dps loss would be marginal. Probably less than 1% difference.

If you want to avoid the Tier IVs you can do

23 determination
33 critical hit rate
19 accuracy/skill speed/spell speed/piety

1 million gil should be enough for that.
