As an experienced player, I hate telling new people that on their path for progression, to do Oz dungeon and collect amethyst fragments to make wolf pieces. Why do I hate it? Because the only thing you're going to Oz dungeon for is the fragments; its a terrible place for money, and it has low rates for shadowdecon/zelunium. Low rates for shadowdecon/zelunium are fine, its an early area for endgame, don't change that.
A few months ago, many endgame areas got adjusted so vendor trash from them became a decent way to make zeny. Could vendor trash also be added to Oz dungeon so midgame people can farm amethyst fragments and make money at the same time?
