Just solod this guy as BST/NIN. Pulled him to the Electrumcap area and just worked BST magic. The only tricky part is avoiding the quadav in the area but it's not too hard. Pets don't last too long, but fortunately this gob is a RNG so he wastes time with ranged attacks. Just refresh your shadows after most pet swaps and you'll be fine. (Only drop was the Letterbox.)
