Black Dwarf

"“The last remnants of a star's life cycle, too weak to be a star on its own. Wipes any tags an ore has, provided it hasn't been looped by its cosmic kin.'"

Overview
The Black Dwarf is a Reborn-tier upgrader released in the Halloween Event 2019: Part 2. It will reset all tags, similar to a Tesla Resetter, provided the ore hasn't been looped by any Star items. (Items include: Morning Star, Neutron Star and Catalyzed Star)

Ores that have been looped through stars then had their tags reset via the Tesla Resetter, Tesla Refuter, The Final Upgrader or The Ultimate Sacrifice will still be destroyed.

A single x5 upgrade from the Catalyzed Star is fine, but it'll destroy the ore if it's used more than once (unless it's sent through another resetting device such as the Tesla Resetter).

Trivia

 * The Headless Baron can sell this item for 6739 Candy.
 * However, OutOfOrderFoxy says it was unintentional, as he forgot that he swapped the ID of Black Dwarf with the Impending Gift of Phantoms.
 * Worse yet, the gift only costs 3479 Candy after its price got reduced.
