Void Idol

"Rare artifact from a time before Hallownest, its spires twined in a unified form. Contains a large amount of liquid from the Abyss, perfectly still. "Inspired or mad, those ancient bugs. They devoted their worship to no lord, or power, or strength, but to the very darkness itself.""

How to Acquire
The Void Idol is found within the Hall of Gods by inspecting The Knight's statue after beating all bosses on Attuned difficulty. Beating all bosses subsequently on Ascended and Radiant each change the idol and its description upon inspecting the statue again.
