Sun Sphere

The Sun Sphere is a Fourth Grade Artifact found in the 1st layer by Riko.

Description
The Sun Sphere is shaped like an egg with a round structure in its center and encasements at the top and bottom covering its exterior glass-like structure.

Upon activation, it emits a bright light.

It was used by Riko and Reg to distract the attention of creatures away from them and enable the two to escape.

It was eaten by an aquatic creature in the Sea of Corpses.

Trivia

 * The Sun Sphere is, alongside the Cradle of Desire, the Princess Bosom and the Thousand-Men Pins, one of the few Artifacts known to exist multiple times.
 * In Made in Abyss: Binary Star Falling into Darkness, Sun Spheres are available from the 1st layer to the 5th layer. Their patterns and structure are more complex the deeper the layer. The Sun Sphere design from the main series is designated to the 4th layer in the game. The different designs correspond to the different egg-shaped relics seen in the Seeker Camp.
