Multiple spell caster classes

[Jason Wedel]

Do you need to prepare an hour per class?

[Drahliana Moonrunner]

I would say yes. You really can't intermix preparing one style of spellcasting with another, especially say arcane and divine.

[James Risner]

+1 yea per class is my reading of the rules

[Drahliana Moonrunner]

Now mind that if you don't need to prepare spells for a class, you can skip the hour for it.

[ForlinA]

Yes, with a separate spell list for each class.
