What is confirmed
A note in the demo says the Nightshade channels embedded powers to its bearer and must spend time in contact with Faye to remain energized. Calvin borrows it while searching for a way to restore her.
What to do
Watch for its reaction near occult evidence and treat mask-related prompts as part of investigation and progression. The mask also frames the talent interface shown in preview coverage.
What is not confirmed
The full ability list, upgrade costs and late-story consequences are not documented in the public demo. Avoid claims that the mask is a cosmetic item or a complete replacement for every detective mechanic.
