So, why no hq Vitriol?

[NJA]

Is this something that SE forgot or am I missing where its farmed at. Was starting to make the 50 hq spirit of salts for the artisans's tool...

Its the only recipe that has a nq only item in it for the artisan's hand in so was just wondering why?

The only way to obtain vitriol is to buy it from the Kobold vendor. Purchase-only items have no HQ version, which I agree can be a pain at times!
