How to Get and Charge the Hypno Device in Graveyard Keeper 2

A player reports buying the Hypno Device from the quest NPC, then charging it at the Formulation Bench with 1 Faith. The purchase report does not name the seller; two replies in that same discussion support the charging route, with one placing the bench technology under Church Lighting.

Hypno Device steps

  1. Check the quest NPC's purchase option for the device. The thread's author says they bought it “from him” but does not identify him; keep the purchased device in accessible inventory.
  2. Unlock the Formulation Bench. A release-build player places its technology under Church Lighting.
  3. Find and use the correct station. Use the Formulation Bench guide if the basement or laboratory wording is unclear.
  4. Interact with the Formulation Bench. Do not use the Story-writing desk merely because another answer casually calls the workstation a desk.
  5. Select the Hypno Device operation. Supply the device and the reported cost of 1 Faith, then collect the charged item.

What “abandoned tower” appears to mean

The quest wording has led players to search for a separate abandoned-tower interaction. Two replies in one release-build thread point instead to the Formulation Bench in the alchemy or basement work area. That is agreement within one discussion, not an official location confirmation.

What is it for? Zombie PR

Players discussing the zombie PR and limit system describe paying to charge Hypno Devices while trying to handle PR penalties. This is the reported context for the device, not proof of a fixed duration, exact penalty-removal rule, or universal cost beyond the one-Faith charging answer. One player says a charged device's PR effect expired on sermon day and they could not pay again until the next day; use your current game's PR prompt rather than planning around that anecdote.

Purchase-option report (single player): The original thread's author says they lost the option to buy from the unnamed seller after receiving the quest and suspects a bug. This is not a confirmed developer diagnosis or a verified workaround.

Language/search alias: Russian-language searches for the formulation or recipe bench—including «рецептурный стол»—should use the existing Formulation Bench page. It is not a separate Hypno Device station.

If the operation does not appear

  • Confirm the related quest step is active.
  • Move the Hypno Device into ordinary accessible inventory.
  • Verify that the Church Lighting/Formulation Bench technology is unlocked.
  • Bring at least the reported 1 Faith.
  • Make sure the station is the Formulation Bench, not the Writing Desk.
Evidence boundary: The get/charge details come from one Steam discussion: a single-player purchase report and two replies that agree on the charging route. The PR-use report is another player account, not an official mechanics walkthrough. Recheck the live quest and workstation after patches.
