Each time the sword is used, its Blessing and power will gradually increase, until infused with Qi again.

Immortal Slayer is a Legacy Artifact which does increased damage the longer it has been flying without recharging Qi.

Obtainment

Learn the Law Exclusive manual from Seven-Slaughtering Sword, 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.

Uses

The artifact deals damage normally like any other artifact following its statistics. Additionally, the artifact does 1% additional damage for every additional second that it has been flying without having its Qi recharged. This makes it more effective against Boss Monsters such as the Phoenix or Torch Dragon, since both of these boss monsters rarely damage artifacts.
