D&D 5E Relative Difficulties of Advancing in 5e

[OptionalRule]

My current 5e campaign (Faerun Adventures) uses XP. It's intended as a fairly low power setting, with no expectation of ever hitting 20th level. After thinking about it, I decided to halve XP awards after 10th level to stop the rocket-boost effect built into standard progression.

This is great. Really this is the reason I even bothered with this post. To be able to adjust something, you have to have an understanding of it's basic behavior. I thought it was worth putting up so DMs didn't figure this out after the party shoots up to 15th level.
