A source of tier V? question mark

[Roth_Trailfinder]

I kind of expected that these recipes were for SB'ing. What Materia did you get?

I am spiritbonding a full set right now. I'll edit this post with results. Remember to repair between quick-synth rounds, a 99-item QS knocks the durability down to well under half.

I like the Aurum Regis Planisphere for getting the Type-1 Crafting Receipt - no timed node mats.

Emerald Soup to hit the Craftsmanship requirement (easily). I'm failing about 10% of the QS. I am not sure if that affects SB speed. After a stack and a half of QS and using a Spiritbond Potion the items are at 40%. ... time passes ...

So here I am, with 298 High Mythrite Nuggets, 29 Griffin Leather Straps, 11 Camphorwood Lumbers, and 6 100%SB'd L180 Accessories. Time to Convert!

Necklace: Craftsman's Competence IV
Earings: Craftsman's Cunning IV
Bracelet: Craftsman's Cunning IV
Belt: Craftsman's Competence IV
Ring 1: Craftsman's Competence IV
Ring 2: Craftsman's Cunning IV

Not a bad haul for the amount of time spent (not counting the time getting the red scrip), but no luck on grade V.

The sad thing is in the time it took you to do this you could've made the money to just buy those materia outright on the MB.
I don't see why ILVL180 doesn't result in guaranteed Grade V for the effort it takes. Or would that be too "accessible", SE?
