Esoterica: Grafted
This six-page supplement presents rules for playing grafted characters in the 4th Edition Dungeons & Dragons roleplaying game. Grafted are beings with metal fused to their mortal flesh, often created through unwilling transformation and treated as outsiders. The booklet covers their origins and roleplaying, along with feats, paragon paths, and emblems—magic items that grant enchantments to natural weapons.
