cursed shore karma vendor selling orichalcum gathering tools
According to my notes (which hopefully aren’t out of date), there is such a vendor in the Fields of Gold (so probably at Caer Shadowfain). ETA: Could be at Penitent Camp also.

Those two places are where you get the axe and sickle, I’ve yet to find a place to buy an orichalcum pickaxe with karma.
