I knew the amount of exp needed per level went up as you leveled up, but I decided to run the numbers and see just how much, visually represented. Figured I may as well share the results so other people could get some use out of it :)

I was pretty surprised by the scale of this. A dragon at level 20 is only halfway to level 25 as far as xp count goes. No wonder people who offer leveling services set a ceiling.
