Combination of skills (skills) (Divinity: Original Sin)

Friends, Hello!

The release brought a feature that many have probably waited.
So now you can combine books skills and get a new (combo) a skill that is not in any school.

For example, yesterday joined some two books of necromancy and geomancy, having the ability that allows you to restore physical protection due to the absorption of the puddle of oil.

So, does anyone know where I can find a list of the possible combinations and their results? Searched the Internet, found nothing.
