How to Solve the Serum Puzzle in BO7 Zombies

To make the Powder of the Forgotten, you’ll need the Necrofluid Gauntlet (a special weapon) and the Wisp Tea perk. You can find Wisp Tea at the Zarya Cosmodrome, or earn it by finishing the twins Easter egg at Vandorn Farm (click here for details). Once you have Wisp Tea, go to the Tailor Shop in the eastern part of Ashwood, right next to Vulture Aid. Inside, you’ll find a mirror that Wisp Tea can break. Activate Wisp Tea by damaging zombies, then simply get close to the mirror – it will interact automatically.
