Wouldn't evocation of flesh disappear after the spell ended?

Not since Chaq left, no. However, if you're going to try making lore, be careful. From what I understand of Evocation, you would have to have an intimate knowledge of how the body works. Which, sadly, at this time nobody does. Otherwise, how would you possibly summon up the correct components?

I'd imagine it'd be ass incomprehensible as how the Clerical-light-healing-orbs heal. I don't believe it would be considered evocation, either.
