Do you take the Literacy skill?

And to "pass on his wisdom to the people," is it necessary for everyone to definitely level up their wisdom? When their priority is the economy. No, but if you have a second combat hero, then it is very much worth leveling up literacy and wisdom, and wisdom for both, but in other cases, it is not necessary.

If you read your latest posts, it is not entirely clear what you want to say: "Why take literacy for the main hero if there is no one to pass on knowledge to...", "...why level it up for this secondary hero, because then you will need to level up other heroes so that they can learn these spells..." - and so on...

Indeed, if there is no goal to have more than one tank hero, then literacy is not needed at all; he will learn everything himself, he will not share with anyone, he will slowly do everything and come out a winner! ;)

The question is - I repeat - how to do all this, only three to four times faster in terms of game time? For this, you need to have five leveled-up heroes and one secondary hero with literacy, who will run around them all and teach them all the same spells. This is faster than dragging each hero to different cities in order to learn magic... Here, the only question is the speed of the game, and literacy is not needed for anything else (as a rule)...

Although sometimes, for example, the only source on the map of such a useful spell as Resurrection is Alamar. Moreover, he is a literate hero by default. And without him, no one will ever learn this spell... Isn't that a goal for a secondary hero?
