Radiant Spark

This shining prism is bound within a golden frame. The bright glow within the artifact is the gleaming essence of celestials bound within it in ancient times. Each activation consumes a bit of this celestial energy, projecting the screams of the celestials into your mind. While holding the Radiant Spark, you gain a +2 item bonus to saving throws against Divine spells and effects and you are aware of its powers. If you are good, while holding the Radiant Spark, you are sickened 3 and can't recover from this condition.

Critical Success The target is unaffected.

Success The target is drained 2.

Failure The target dies and its essence is trapped within the Radiant Spark. It can be brought back to life only with powerful magic such as Wish or Miracle.

Critical Failure As failure, and the target can't be brought back to life until the Radiant Spark is destroyed.

Destruction An archfiend or evil demigod must willingly swap their essence with that of a celestial dominated or bound by the artifact, then critically fail the saving throw against having their essence consumed. This permanently destroys both the artifact and the fiend or demigod.
