The weakest castle in Heroes of Might and Magic IV!

How will you level up only the Knight? Separately. And even then, it takes time. I won't just sit around either.

I'll level him up on the way to you. I'll take the Mage with me. In battles with neutrals, you can even manage without the Mage. It's enough to give the Knight the Magic of Life spell of rank 1 in the seminary.
