What should I do after reading Wizard 3?

After reading the book, sell it to bookstores, weapons dealers and armor dealers. In this way, the merchants who sell these books at the highest price will lose a lot of money.

All the books you have read can be found in your catalogue book fascicle. I have sold all my letters to the bookseller in Novirena. If you want to buy it back, you can keep the change. Moreover, the shopkeepers in the city are really rich, and the prices of books sold to them are higher than those in other places. Like a blacksmith who lives in a city and opens a shop, he can sell it at a higher price.

Books and letters don't seem to carry much weight. There are books everywhere, and there is nothing to sell after reading them. When you start playing, it is enough to leave a set of equipment and one or two handfuls of steel and silver. There is no need to leave too much in the backpack, because the upgrade is fast and the equipment is everywhere. You can choose equipment purposefully after the suit task.
