I'm a big fan of the whole phyrexia idea from Magic the Gathering. I've been toying with the idea of bringing them into my games. some of the ideas i've had are working out well, i was wondering if anyone else has used them and if they have any advice and such. so far i'm using the artificer from Eberon, the soulforger from quintessential wizard, and some of my own ideas. i haven't made either the stats for the Phyrexian plane (don't have the Planescape book) or Yawgmoth the god yet. i'm looking for rules on altering the body with metal and such. i know there was a section in one of the dungeon or dragon magazines on grafting metal to your body i just forget which one. any one else remember? hopefully other people can give me some other options.
I know one of the Eberron supplements (Magic of Eberron I believe)has warforged grafts that would work well with Phyrexians
