would really love to see the Urn of Shadows with a grip and chain as a Spirit Breaker flail. the item is pretty awesome on the hero, so it makes sense. add smoke effects like on the icon, and voila: it blends in with the other flails and makes a great cosmetic.
i suggested this on the dota forum few days ago and got some positive feedback, would be glad if someone could create the item. (might add a picture later on)
