Crows/Crow's Special Brew

[Verdandi]

There are two items in game with nearly identical names:
Crows Special Brew which is the original, old world item that is known to be usable in pottery vial recipes; and
Crow's Special Brew, which is sold in Goru'Kar Mesa

They are definitely two different items. Can anyone confirm whether the Crow's version works in those same pottery recipes?

No Darius in Goru'Kar Mesa

Trellos, a druid, ran the entire zone Tracking for Darius. Darius is a myth. No such hombre.

Google search reveals that Alla has a level 45 merchant listed, but no location, picture, or comments.

Another Alla's page has a Darius listed in conjunction with a Mesa quest, but only to get Celestial essence from the PoK vendor by the fishpond.

Other than those two, and the few spots in EQTraders. no Darius to be found in Gor'ukar Mesa.

I've personally confirmed that Darius exists. However, he (and three other merchants) only spawn when you complete a quest chain in the centaur camp that involves killing the undead specter haunting the area. I don't know how long they stay up afterwards, but it's at least a couple of hours.

Darius ain't an Aquarius

Thanks, I found him. I couldn't get the quest, because I had already done it, but it turned out that I only need to kill the Shade of Corruption to get Darius to spawn. He has both types of brew and I bought both and attempted combines with both.

Darius
Gorukar Mesa 516, -864 (NE evil centaur camp)
Only appears when the Shade of Corruption has been killed.
