Effective way to have many spells?

Is there any effective way to have many (50+) spells on a unit? I am open to anything, dialog menus, multiboards, whatever. I have another question: If a dialog menu had more buttons than could fit on the screen, would it gain a scroll bar?

theres a way to do more than fifty but if i remember its just alot of dialogs and no, dialogs just go out of the box's is my experiance....

You would have to use multiple pages (Next Page Dialog Button) for a really long dialog

[you could try using the ability 'Spell Book'... if you want try and mess around with it... it's nifty]
