This is great content, I'm impressed by the whole mod especially the changes made to fiends. A few minor things I've noticed
- Fiends summoned by the player do not attack liches for whatever reason.
- From what I see in the files gelugons only get an 3 APR when they should get 4
- Pit Fiends according to 2nd Edition manual have a base 6 APR, since it looks like the highest base you can set is 5 maybe just consider giving them a permanent haste.
It would also be nice to add an option for 50% increased hp of fiends like SCS has (meaning +50% from the PnP values). It just doesn't make sense that your fighters can have more hp than a massive demon even if it's not PnP accurate. 1 or 2 hasted level 9 fighters can take out a pit fiend in a few rounds without trouble.
