**Players can repeat the Battle for Azeroth trial experience with up to 12 characters per qualifying account during the welcome back weekend. The Battle for Azeroth trial experience ends after three hours of game play in Battle for Azeroth, or after the quest "We Need Each Other" (for Horde) or "A Nation Divided" (for Alliance), whichever comes first.
Although the Battle Pet Trainer will only offer to teach you your race-specific companion, it is possible to add all of these pets to your collection. You can either find them in your faction’s auction house or you can create a character of the race whose pet you would like to learn. Using your new character, you can seek out any battle pet trainer in major cities. After you learn the pet, you can delete the character; the pet you learned will not be removed from your collection.
