Jass, my apologies.
The concept is that you have 7 different abilites, but you can only learn 4 of them.
Thanks for the tips, I'll look in to spellbooks.
"You can also pass the normal limits of the editor by pressing Shift while doble clicking on the line in object editor." - I tried this, but only 5 of 7 abilities show up when trying to learn new abilites. So no, that doesn't work
