Instructions
Finish your battle first. Revive Pet takes 10 seconds to cast, making it difficult to cast during a battle without being interrupted.
Walk to where your pet died. If you cannot remember exactly where your pet died, look around until you find its body still lying on the ground.
Click the icon on your action bar that shows a hand. This is the Revive Pet spell. Wait 10 seconds for the spell to cast; it will bring your pet back to life.
