  • The first Tome used by a team only grants the base experience. Each following Tome used by the team grants 135 more than the previous Tome.
    • There is no stack limit to this, so the effect keeps on getting stronger with each Tome of Knowledge.
  • Can be used even when already at max level, wasting the item.





  • As it is cheap and grants a fair amount of experience in exchange for those coins, it is advisable to buy it whenever available.
  • The higher the level of the hero is, the more experience is required to level up. So it can be better to use it on a low level teammate as they get higher use out of it by reaching crucial levels early.
  • Ideally, a team could choose to have their carries use this item to speed up their growth. On the other hand, the supports could be chosen who may need just a little boost to keep up with the rest of team as they purchase wards and other support items.
  • Use the Tome of Knowledge to achieve crucial levels, such as level 6/12/18 to unlock important ultimate abilities or 10/15/20/25 to unlock talents for the next teamfight.
