Artifacts

An artifact is a mysterious object that has appeared on Earth.

Overview
Artifacts are mysterious but powerful objects that were created by Luna. These objects grant different strengths depending on the item. The Nyoi-Kinko Staff, for example, grants Shen the ability to reach super long distances with the staff's extending capabilities. Artifacts are collected by the Union in order to gain more power. Artifacts can become stronger depending on the wielder's mental and emotional strength, even triggering an "evolution" in certain cases.

Some of them may contain memories of previous loops of the world, examples of these are Apocalypse and Fuuko's Revolver Artifact.
