Right before they removed the cargo hold NPCs, I bought up a couple years' worth on the offchance they'd still work (they did). I could still see Gurvall's pretty face today if I hadn't trashed the rest of them, but I got tired of the inventory space.
I took this screenshot a while ago as a sending-off. +2 guild bonus to hit and damage that stacked with everything else, no matter what anyone else said... (tested with Good Hope, and pretty much everything else). And a good friend... you will be missed!
