Desynthesis Endgame Guide

That's not %, that's SE's arbitrary stat that tells us pretty much nothing, just like reduced durability loss. As far as I can tell, NQ is +2.5% so HQ is probably +5%.

I thought it "gave" you 1 point of desynth skill in every class. So desynthing an item at say 70 skill with food and 71 skill with no food would give you the same % chance.
