I was looking into how to HQ items as a lvl 50 Culinarian. In my search everything seemed to be time stamped from a few months ago. I was wondering if there have been any updates in what cross classes you need to HQ?

I already have....
Culinarian lvl 15: Hasty Touch
Culinarian lvl 37: Steady Hand 2
Leatherworker lvl 15: Waste Not
Weaver lvl 15: Careful Synthesis

I have heard that these cross class skills are a must...
Alchemy lvl15: Trick of Trade
Goldsmithing lvl 15: Manipulation

Is this true? Am I missing some abilities?
