There are several different types of resources expended by player, NPC, and vehicle abilities. All classes in World of Warcraft have access to at least one primary resource, and several specializations grant access to additional, unique resources usually related to the role that specialization performs in combat. Resources are often related to the lore surrounding the class.
Outside of boss encounters, NPC abilities are typically limited by their combat AI or cooldowns rather than resources; most NPCs have an irrelevant mana, rage or energy bar depending on the particular mob type. Players use their abilities considering primary and secondary resources, cooldowns or a mix, choices determined by class, specialization and talents.
Resource pooling is a strategy used to manage resources so that they could be consumed most efficiently.
