Do you take the Literacy skill?

I've kind of forgotten a bit.
Do both heroes need this skill in order to learn a spell?
Or is it the teacher who needs the skill, or the other way around? =)

No, not both. It's enough for one hero to have Literacy; then, when they meet any other hero, they will exchange spells – that is, he will teach the other, and he will learn from the other.:smile02:
