From publisher blurb:
Grafted are not born. They are created. But few come into being willingly. Whether an innocent lifted off the streets, a criminal condemned to torture, or an insane mage that took his experiments a half-step too far, the grafted are forever marked as outsiders. Their mortal flash fused with metal, the grafted must find their way in a world where a grafted's blades signify all that is pariah. This six-page booklet includes rules for playing a grafted in the 4th Edition Dungeons and Dragons Roleplaying Game. Herein, you will find;
How to become a Grafted, a being who has had metal fused with their mortal flesh.
Information regarding roleplaying a Grafted.
Feats and paragon paths for Grafted Characters.
Emblems, a new form of magic item that bestow enchantments on natural weapons.
