Neon Abyss 2 Acid Token: What the Collected Source Says
The Neon Abyss 2 discussion describes a Butterfly Token, not an Acid Token. Review the single player report and its limits before using it as a route.
The Source Does Not Mention an Acid Token
The collected Steam discussion is titled “DARK ERIS.” A player asks how to unlock the boss, and another commenter describes a Butterfly Token. The thread does not use the name “Acid Token,” and it does not establish that an Acid Token and Butterfly Token are the same item.
One Player's Butterfly Token Report
The commenter says they completed the Faith of Psychedelism, entered a butterfly room, and chased butterflies that could drop different effects. They report that carrying a Butterfly Token after defeating the EDM boss led to an extra level where Dark Eris appeared.
This is one community report from August 2025. The collected reference does not independently verify the steps or show whether they remain current. Treat it as a lead to test, not a guaranteed route.
What Is Still Unknown
The Steam discussion about Dark Eris does not explain an Acid Token's location, effect, drop chance, or relationship to the Butterfly Token. It also does not compare different routes or give a developer-confirmed checklist.
