Desynthesis grayed out

[Iscah]

Those items don't even show the menu option for desynthesis. Their issue is the skill level issue.

This is an old post, but in any case you can also desynthesise from the main inventory menu, not the dedicated desynthesis menu. I'm not sure if the option shows for things that can't be desythesised at all, but it certainly does and is greyed out of you could do it but haven't reached level 30 in that class yet.
