It is produced from another Artifact, the Stairway of Light.
It emits a band of light that reflects and hits the intended target. It has the capability to hit whatever object its user concentrates on.
It can also fire at multiple targets, including those that aren't in its direct line of fire.
- At one time, it had been assigned the auction name of Stairway of Light and, even after being processed, people still refer to it by that name.
