OK.....there is a massive difference between knowledge and experience. He has knowledge of a bunch of runes and learned a couple of arrays that he JUST learned a few hours ago. Yet suddenly he's tossing dozens of arrays out during combat with CULTIVATORS..... he doesn't have the time. And I would argue that his speed of creating arrays would not yet be up to that. Just as there is a massive difference between knowing a programming language and actually writing programs.
