Pet System¶

How hunter/warlock pets and guardians are stored and powered. Sources: src/game/Objects/Pet.cpp, src/game/Objects/Pet.h.

Definition Tables (world DB)¶

Table	Purpose
`creature_template`	Pets are creatures: `type = CREATURE_TYPE_BEAST`, `pet_family` selects the pet family, `spell_list_id` / `pet_spell_list_id` define autocast pools.
`pet_levelstats`	Base HP/mana/armor/damage per creature entry and level.
`pet_spell_data`	Autocast spell pool per pet (referenced by `pet_spell_list_id`).
`petcreateinfo_spell`	Spells a pet of a given entry knows from birth (patch-filtered).
`pet_name_generation`	Random name pools for wild/tameable pets.

Table (characters DB)	Contents
`character_pet`	The stable: current pet + stabled pets, stats, rename state.
`pet_aura`	Auras persisting across logout.
`pet_spell`	Learned spells.
`pet_spell_cooldown`	Cooldowns.

Controlled pets run PetAI; EventAI-marked pets are upgraded to PetEventAI (see Creature AI System).
Happiness/diet feed the loyalty system; growth uses pet_levelstats.
Charmed creatures (mind control) use the charm spell pool from creature_charm_spells.
