Lineage 2 archers will love this. It essentially allows infinite storage of whatever supplies you want to carry. Grab a pet and throw whatever inventory you don’t have room for on the pet. Each pet can carry the same amount of inventory. So, a wolf pet has the same inventory space as a dragon. This means you can use a wolf pet as a mule to carry your arrows or other supplies that you need in the field and instead of going back to the vendor/bank over and over.
