Moon Wolf pets are similar to the other Non-evolvable pets in the sense they start from level 60 and have no skills. They will also take up a pet slot, have loyalty, and can be ridden. They are obtainable from the Moon Wolf Lucky Box.
Like Unicorns, the Moon Wolf can "evolve" to become a True Moon Wolf and an Ultimate Moon Wolf. True Moon Wolf require two level 65 Moon Wolf while Ultimate Moon Wolf require two level 70 True Moon Wolf. The primary difference is in their appearance, where they will sprout armor and begin to glow. You will need the True and Ultimate Moon Wolf Alchemy Scrolls from the Item mall to do this, based on their respective kind. Actual Alchemy or High level alchemy is not required for this.
