First bubble needs revision. The most natural way to interpret "bestow a price upon" is "put a (literal) price on something (so it can be sold)", which is clearly incorrect. Based on context, I imagine something like, "the more you value/cherish me, the more power I'll give you" is more accurate.
The greater the price you pay, the greater the power that is bestowed upon you.If you do, you will be even stronger.Won't you offer more to me?What? You want to get stronger by your own means?
