I now can make the tomes actually charge the correct value to start with so that instead of taking 3500 and then giving you 2500 back it will just take 1000 as originally intended. Note that this will logically only effect when you are able to buy the cheaper tomes as you will be able to get them at 1000 instead of waiting for 3500. When your above level 5 you will still as always need to buy 3 3500 tomes before being able to buy the 1000 tomes.
