Here are the basic changes:
1) Dual NPC stats.
2) I tried to verify that the skills used are available in Classic. If they aren't, I give a note of what maneuver to make in both versions. There's also a note at the beginning stating that if the skill is in Classic but you don't use it because its optional, you'll need to replace with a stat maneuver or the skill you'd prefer.
3) I left the lists from Channeling Companion alone because if you have Channeling Comp they'd be usable in either version and if you don't you can't anyway. For instance, Weracy still knows Ceremonies in RMC.
4) Monster stats didn't change between versions so I left them alone.
5) Lots of profession notes now have two entries (Layman/No Profession, Mythic/Rogue, etc).
6) I think I had to leave Holy Arms as a spells for Angels, because there is no RMC equivalent. I stated that it's only there if you have the spell list, however, otherwise you can ignore it.
7) I changed references to levels of success in RMFRP to the numbers you need to roll, for RMC (so it's no longer success, but 111+ if that's the target number, to avoid confusion).
I stated out the affects of Holy Aura in the angel so that RMC people know what it does.
I think that's it. Feel free to speak up (and soon) if you feel I missed something or want to raise a fuss.
