Manifests as a floating, glowing item card with the signature comic book aesthetic - thick black 'inked' borders, halftone shading in deep grays, and neon green spectral energy emanating from the edges like burning fog. At its center, a stylized open eye watches perpetually, its iris flickering between gold and green. When activated during a tag claim, the eye narrows and the words 'CLAIM RECOGNIZED' appear in jagged onomatopoeia font. The card hovers above the holder's actual bag tag, overlaying it with undeniable authority.

The Phantom Claim serves as the ultimate authority in the Relic Exchange. It grants automatic validity to any tag claimed by its holder, making stolen tags uncontestable. When two players dispute a tag transfer, the Phantom Claim holder's version is always recognized as truth. It flows between players based on achievement and honor, appearing each season to whoever demonstrates the most uncontestable claim to stolen relics.
