The Spellbook allows players to inspect and change the abilities of their streamers and pets. It contains an overview of the known and unknown abilities of the streamers and pets. When players build the Spellbook, they unlock streamers' auto-skill abilities, increasing their effectiveness in combat.
Unlocking and Upgrading

For example, a hunter might have chosen the multi arrow ability, an ultimate skill, and selected the stunning trap, an auto-skill. From this point on, not every ability will be available because they have not unlocked all ability-sets.
Players unlock ability-sets by sacrificing streamers or pets in the Upgrade building. In fact, when players sacrifice a streamer or pet, their ability-set becomes available for use.
Streamer Ability-SetA streamer ability-set contains one ultimate ability, and three auto-skill abilities. The ultimate ability activates every 3 rounds in combat, and the auto-skills activate every round (depending on the ability).
A pet ability-set on the other hand, contains one auto-skill ability, and three passive abilities. The auto-skill activates various streamers in combat that have the pet guardian active (see the Loyalty Tree pet guardians), and the passive abilities provide buffs for various areas of the game when the pet is active in its respective hatchery (see Geopet GO for more).
