After our discussion on the topic of the expense of learning mystic powers I've changed the cost of learning Mystic Powers. Whereas they were 100 * Mystic Power Level, they are now 10 * Mystic Power Level. I am also considering allowing the GM to override that number with a text box value, but have not implemented that at this point. So now Fire Bolt (1st Level) costs 10 Iron to learn, rather than 100 iron. That seems a lot more reasonable, and affordable for characters.
