Desynthesis Endgame Guide

[Nyalia]

Is there a cheaper way other than cashmere for weaver desynth around level 90?

Run the new dungeons and use the tokens there to get Myth gear that can be desynthed by a weaver. Or, run coil turns 1-5 (except 3) for equipment that can be desynthed by a weaver. I recommend T4 as as SCH, WHM, BLM, or SMN, as they can Need on two WVR-desynthable pieces each.

Those are the cheapest ways, if slow.
