question in the thread title, just wondering what it did. I may have known once, but hiatus took the knowledge from my dusty brain.

Tomes in general give your pets stats when you use them. 1-3 stats at random in all. (Level, strength, defense, health, speed, intellegence)

You can also read it to your pet as a normal book.

Thank you. I owe you my life.

Happy to help! ^^
