Adding to Spellbook

I don't suppose there is a way to add and remove abilities from a spell book ingame is there? That would be totally awesome if there were.

Yes there is, use another spellbook that contains the spell you want to add. Then add the new spellbook to the unit and DISABLE the new spellbook for the owner of the unit

Hmmm... so are you saying I need to make 32 different spell books for every different combination of spells (if I were to choose six spells) available in the spell book?

No, just create a spell book for each ability.

Thats adding, so for removing you enable the new spellbook and then remove it?

What about when you level up spells? How does that work? For instance with a hero ability, how do get it to show only in the Spell Book.

do not need to enable the new spellbook, just remove it.

To level up a spell that was added by a spellbook, just imagine that you are leveling up a spell that is outside the spellbook the same methods work
