Vortex Orb

Vortex Orb is a Legacy Artifact which increases in damage the more enemies it has killed.
Learn the Blood of Asura Fragment manual (obtained from Second Golden Casket or a random drop from Ancient Cultivators), and craft it with an Artifact Crafting Skill Level of at least 20 to obtain the Incubation item.
Kill the required number of beings to receive the legacy artifact, which can then be claimed, locking the item to that cultivator. The beings can be of any race, including animals, humans, YaoGuai, or Monsters. Invaders are a good choice for this with enough Reputation.
