Pets can be found in a Bestiary which allow you to buy a passive companion that can help in battle. Pets can be purchased for Orn. They come in different tiers. As of patch 1.11.0 you can store your pets in your Keep, with more storage available in a higher level Keep. When you purchase a new pet, you will lose your old pet if it is not stored. Higher tier pets can be found in a high level Bestiary.

The level and stats of your pet scale with your level, and will always match whatever level you are.
