how to use other spell books

[Sotj]

if you have more than 1 caster, how to swap quick bar into other spellbook?

[Sotj]

wtf, you cant swap it anyhow and you cant add those spells from pressing B either... So if you have like 19 levels of cleric and pick one level of sorceress, you may never use your cleric spells again

[Sotj]

nvm I think it bundles everything into same book.

Classes using charges instead of copies of spells don't really use the spell window.
If you mix cleric and druid for exemple, normaly you should have 2 lines on the left page of the book showing the classes able to do spells and clicking on one will get you to the spells of this class. Af far as i know only Mystic Theurge prestige class mix all spells together at once allowing you to also get copies of spells that normaly uses charges.

on the spellbook menu there are icons to click for the different spellbooks you have

outside of it, spellbooks are combined into the same one
