Oh, how long have I been searching for something like this!

Question though, how did you come up with these prices? What sort of math or logic did you implement?

I ask because a vorpal sword is legendary and its 24,000gp. Considering the crap ton of gold the tables start giving out around the teens, it seems like it would be super easy to come up with this much to grab a couple of vorps, which seems off.

I just want to know how you did it so I can understand it so I can use it properly.
