Hello, I have a problem and I hope you can help me. In game, there is a bar with spells/actions etc. that shows itself after I click on my character. My companion, Aloth is lvl 3, he has learnt some 3lvl spells and he has them in the book he is currently using. The problem is that those spells are not visible on the action bar, there are only spells of first and second lvl. Could you tell me how to change that?
