In-game Hotlink: Book of Econ 2
This single use item can be used to permanently increase a player's selling slots for the Player Market. Each use consumes one book and provides one further slot, up to a maximum of 10. Once 10 slots have been unlocked a Book of Econ 3 must be used to unlock further slots. Since a player starts with 3 unlocked slots, ONLY 7x Book of Econ 2 or 2x Book of Econ 1 plus 5x Book of Econ 2 can be used per player.
