Looking for imput, valued EnWorldians! I've read a couple of different things here and there that have led me to believe that devils don't stay in one form forever. You're not "born" a Pit Fiend, you advance there from earlier lesser forms (lemure, imp, and so on) but I've had trouble finding anything clear about it. Are there rules for this somewhere that I'm missing, because I really like the idea. X number of years of service, and you get to be a bigger, badder devil to do even more evil in the world. If I can't find the "evidence", I'll HR it anyway, but I'm currently attempting to convince my DM to let me advance my imp familiar in our evil campaign, and I think it would be a lot of fun. Thanks in advance.
