Is it bad that when I first started reading this thread, my mind went to a slightly different area? Sorry for possible thread jacking, btw >.< Hate doing that...
http://www.youtube.com/watch?v=JZBAEk_UgmkIt then made me think, how to stat out Shiro Emiya, and in turn, Archer's ability to materialize weapons, and even greater Artifacts, for lack of a better term, in order to fight his enemy. I thought it was kinda silly, but then realized... The magic system fits perfectly for some of Archer's more powerful attacks.. You just have to be open minded, and see the attack as a summoning of a powerful weapon of lore, which is capable of doing spell equivalent damage.
He would be a Focused Practitioner, with a Channeling of Materialization (Conjuring), and a Ritual of the same thing. Since he is the literal pinnacle of a weapon Conjurer, and would probably have some decent specializations in it as well, I could see him easily being able to summon some of his normal weaponry with a "quick" ritual, while some of his more powerful abilities obviously fall under evocation, or very elaborate uses of his Ritual casting... Btw, if you can come up with a better idea for Channeling, or Ritual that could fit better for his ability to both Conjure, and Reinforce real things, then be my guest... Running on little sleep again >.<
Should have NEVER attempted to piece something like this together, but I just couldn't help myself... Fate/Stay Night is awesome and epic. Cheers
