Desynthesis Endgame Guide

[Nyalia]

So not to hijack the discussion, but has anybody found a use for Cul desynth? It was basically useless in HW and I haven't found anything so far in SB.

Check here for specifics on what you can get, but the only items from 4.0 that at least sort of have value are grade VI combat materia, which are likely infinitely easier to get via other methods (like tanking leveling roulettes). So, in other words, not really. =\
