When a game gives you the ability to make the zombies work for you, you are bound to run into strange devices and people asking for unusual requests. In Graveyard Keeper 2, while some requests are pretty simple, as most of the demands can be completed via crafting, other requests will put you on a path with little to no information about the objective. Charging up the Hypno-Device is one such request that will confuse most players when they come across the quest.
The request is pretty simple, but the difficulty arises when you are trying to find a way to charge up this device. Here, I will help you find a way to charge up the Hypno-Device to complete the quest Congregation Table in Graveyard Keeper 2.
Making a Charged Hypno-Device in Graveyard Keeper 2

You will need to interact with the Formulation Bench to charge up the Hypno-Device in Graveyard Keeper 2. In the quest “Congregation Trouble“, Gunter will appear at church and begin a conversation about fewer people attending the sermon, and he will put the blame on you for working with zombies in the base. After the conversation, meet Gunter again at the Observatory and bring up the topic “Problem at the Church”. He will give you the objective of charging a Hypno-Device, a way to deal with the public panic. Once the conversation with Gunter is complete, he will raise the shop-tier and start selling ordinary devices and charging recipes too.
- Buy Hypno-Device: Talk to Gunter in the Astrologer’s Tower to buy the Hypno-Device for 50 Copper. He has 10 of these devices ready to be sold in the shop.
- Charge Hypno-Device: Now take the Hypno-Device to the Formulation Bench in the Writing Basement found inside the Abandoned Tower. Interact with the Formulation Bench to charge up the Hypno-Device by spending 1x Hypno-Device and 1x Faith.
Formulation Bench Details: You will find the blueprint for the Formulation Bench under Church Lightning I, following Church Cleaning in the Theology section of the Tech Tree. You will need 5 Red, 10 Green, and 5 Blue to unlock Church Lightning I. You can build the bench at the Writing Room or Alchemy Lab by spending x4 Wooden Plank/ x4 Bronze Detail/ x1Polished Bronze with Building Mastery 2.
Once you have a Charged Hypno-Device in your possession, head over to Gunter and hand the device over. Gunter will ask you to hold the next Sermon to test the Hypno-Device. Now the route is pretty simple; just head to the Church and hold a Sermon. You don’t have to do anything manually; everything will happen on its own. Once the Sermon is over and you are looking at the results, the device will trigger. Long story short, the device will not solve the panic problem, but you will leave the quest with 10 Reputation with Gunter, and you will have a brand new PR machine in your base.
Charged Hypno-Device : Uses
There is more to these devices than just finishing off a random quest. The quest serves as a starting point to make use of these devices to make the zombie workforce more efficient. Now, any Charged Hypno-Device you have or create will be taken by the PR machines to raise the number of zombies you can support per week.
- PR Machine #1 | +10 Zombies limit for 1 week. (2x Charged Hypno- Device)
- PR Machine #2 | +20 Zombies limit for 2 weeks. (3x Charged Hypno-Device/ x10 Any Newspaper)
- PR Machine #3 | +30 Zombies limit for 3 weeks. (5x Charged Hypno-Device/ x20 Any Newspaper)
- PR Machine #4 | +50 Zombies limit for 4 weeks. (x100 Any Newspaper)
- PR Machine #5 | +80 Zombies limit for 5 weeks. (x100 Any Newspaper)
Note: The gluttony symbol indicates the machine supply; one thing you should note the increase in the workforce is temporary. In short, it’s a temporary buff; you are not removing the limit permanently in the game.
As you can tell, running zombies and making them the primary portion of the workforce requires maintenance, and Charged Hypno-Device plays a key role in the ongoing cost of the maintenance. If your workforce entirely relied on the zombies to carry the heavy load, Charged Hypno-Device would be a crucial ongoing item. Get Universal Bags and Big Universal Bags to carry stacks of Charged Hypno-Device with no issue.
You must get into the gameplay loop of buying the Hypnotic Device from Gunter and charge it up via the Formulation Bench. Now it’s all about feeding the PR machine with the stream of Charged Hypno-Devices to support the undead workforce.
