Plasma Crystal Ball

Plasma Crystal Ball (Korean: 보라 광선 수정 구슬, bola gwangseon sujeong guseul, "Violet Beam Crystal Ball") is an Epic Treasure released alongside Prophet Cookie in the first half of The City of Wizards: The Wizard Archives update. It summons a Plasma Ball which fires plasma at upcoming Jellies, magnetizing them and making them worth more points.

Story
''A crystal ball emitting a celestial, purple glow. Its otherworldly nature seems to have an effect on Jellies.''

Trivia

 * Prophet Cookie, Chestnut Cookie, Pudding Cookie, and Alchemist Cookie appear in the promotional image for Plasma Crystal Ball.
 * Plasma Crystal Ball and $π$ seem to have a similar effect, in which they both fire some sort electricity at Jellies, causing them to magnetize and be worth more points.
 * This Treasure appears in a cutscene for the The Treasure and the Crow story.
