We hold these truths to be self evident.
Multi-classing
[spoiler]-Experience penalties are waived.
-Favored classes are ignored.
-Any class feature penalty for multi classing (like Paladin divine spellcasting) is ignored.
-EXCEPTION: If you dramatically shift alignments or start taking a class that is thematically or RAW of opposing alignment, you will lose access to your divine spells from the previous class. [/spoiler]
Class Restrictions
[spoiler]-Druid shapeshifting is changed. The character is limited to a number of available forms depending on level, scaling from 1 to 6. I'll flesh this out if I need to make Druid NPC or either of you want to play a Druid.
-Any classes that require you to be evil are banned. You're supposed to be the good guys here. [/spoiler]
Banned Books
[spoiler]Tome of Battle & Tome of Magic. I'm not interested in trying to balance around their goofy classes and feats. I've read them, I don't like them.[/spoiler]
