Thanks to both of you for the helpful anwers.
Albeit I knew it was a narrow market, I was already worried that I broke a rather valuable item after all after seeing a three digit ecto price in Kamadan.
Since, especially because it is a narrow market, gold rarity could have been a bigger selling point than being the highest damage available for its requirement.
(I also heard that they were used by some R/A builds to make speedclears slightly more speedy.
But q5 daggers appear to be the relevant choice here.)
