Imagine you go to buy a car for £15,000, and then the dealer or company says, we can give you this addon to your car, say leather seats, for an extra £500. Would the leather seats cost £500, or cost £500 + "the total cost of the car" = £15,500. Most people would think that the claim that the leather seats cost £15,500 was an unusual or odd way to think about their cost, given that you're already spending the £15,000 anyway.
You're spending the mana on rejuvenation anyway. For 6000 more mana, you can have this 400k heal. How much does the extra heal cost?
