 * The initial replenish time provides 2 tomes at once in the shop. Following replenishments provide single tomes.
 * Stacks with itself in the inventory. There is no stack limit. The sell value adapts based on the number of instances in the stack.
 * Tomes of Knowledge are fully sharable.

Tips

 * Because Tome is relatively cheap for the amount of experience it provides, it is generally advisable for someone on your team to buy and use it about as soon as each one becomes available.
 * Because it takes more and more experience to level up the more a hero levels, the experience bonus is technically more relevant the lower its user's level. For example, a hero that is nearly lvl 5 can use Tome to jump all the way to level 6, while a hero that is lvl 24 might receive about 1/3 of a level from the same tome.
 * It is recommended that your team allow the first tome to be consumed by someone that is not yet Lvl 6. Ideally, they then use their newly acquired ultimate ability to make a play (such as, to kill an enemy hero) for immediate pay-off.
 * What your team uses any further tomes for is more debatable. Tomes can be used to put your core heroes even further ahead, or they can be used to help your lower-leveled heroes catch up. In general, they should be used to help your team achieve key hero levels, namely 6/12/18 (for ultimates) and 10/15/20/25 (for talents). Keep in mind that some ultimate/talent upgrades are worth much more than others.
 * Tome of knowledge is also affected by exp. gain talents which means that if a hero has a 10% increase experience gain talent, then that hero will receive 770xp (if used at exactly at the 10 minute mark, numbers may vary higher) instead of the flat 700xp.
