I'll fix the Core Beliefs.

Two main reasons: As you stated before, what a character doesn't understand fully about what they're doing is powered by pure, raw magical energy - a presumably finite resource. Patrick can't use it 24/7 to get him out of trouble, and thus has relegated it to either emergency use or travel. The other reason is that Patrick loves technology and innovation. Something he really wants to create, or at least see, is a successful suit of magitech armor.
