Mmmm...This was hard, I wanted to say yellow gemstone, but I really don't have a problem farming those as much as red XD...plus a lot of players sell them now so it isn't so bad.
I think for quivers if we can set it somehow to not give immaterial arrows it should be fine, I think immats need to stay kinda annoying to get as they are extremely powerful :]
