Ok, of all the Tier Ones, this is the one I have the least experience with. If I were to build a medieval Bruce Wayne out of an Artificer (or most likely a Psionic Artificer), how would I go about it? I would imagine it's the concept that fits the best (keenly intelligent, competent in combat, gifted in design tech, but still human-i.e. d6 HD), and from the sounds of it they're capable of replicating absolutely anything, given time. So let's have at it, let's make the Batman.
EDIT : Though don't think that limits you to Human only...this is CO afterall
