InKingdom Come: Deliverance 2Prevention is a side quest and part of the Mysteria Ecclesiae expansion chain. As part of it, you will have to create a plague suit. To do this, you will first need to find mint, rope, a piece of leather, sage and a recipe for aromatic oil, and then prepare it at the alchemy workbench. If you have difficulties receiving or completing the quest, then study our guide.
Completing the “Prevention” quest in Kingdom Come: Deliverance 2
How to start the task
After completing the previous task – “Anamnesis” – you will continue the conversation with Albicus and Zachariash. Say “Help is always welcome”to find out what to do next. The doctor will ask you to search the crypt, but before that you should make a mask and hood to avoid infection. For this reason, the “Prevention” mission must be completed BEFORE going to the crypt and taking on the “Silent Witnesses” quest. If you go to the burial site without a mask, you will receive a permanent “Disease” debuff, which will reduce all your characteristics, which can significantly complicate the completion of the following tasks.

Having started the desired mission, you can talk again with Zachariash (the doctor) in the infirmary to get tips from him on finding the things you need. We also recommend that you select the answer with the gold icon: “Can I help you?” and follow through with the conversation to mark his guard Denek with a side quest icon. Chat with the guy for another task that can be easily missed.




Remember that to open the “Benefactor” trophyyou need to help the inhabitants of the monastery by fulfilling their additional requests. These side effects can easily be missed if you progress too far into the expansion's story. Please note that right now you can complete the following quests:
- Our Daily Bread – required for the “Benefactor” and “Ostraconophobia” achievements.
- Prediction of Evil – to start it you need to talk to the librarian Crispin during the previous quest and choose an answer that does not require a stat check.
- The Last Wish – to start it you need to chat with the monk Afanasy, who works on the floor above the library, or with Konstantin in the garden.
Important: You may fail the “Quiet as a Church Mouse” achievement if you get caught by the patrolling knights, causing them to escort you back to the infirmary. Thus, you will need to stealthily move around the monastery until the end of the entire expansion story if you want to unlock this trophy.
Find the rope
The description will indicate that you can find it near the construction site, so go inside the church, where construction is currently underway. The desired location is located just west of the highlighted area marked “Search the crypt.” The bast rope will lie on the floor, right next to the hole. There will be two workers wandering around, whom you can distract with the help of stones – then grab the rope and run away.



If you really don't want to get noticed, there is a more discreet way to get the rope. To do this, go to the scaffolding north of the monastery and climb onto it using the wooden ladder behind the white blanket, and then enter the building through the window. Climb the stairs to the inner scaffolding and move left, then go down and go to the hole, near which you will find a second rope that you can safely pick up without attracting anyone's attention.






Find a piece of leather
Any leather will do – pork, deer or cow. For example, you can findpigskinin the northwestern part of the location, not far from a small house. It will simply lie on the barrel, to the right of the building, that is, you won’t even have to steal it from anyone or pick locks.




If you couldn’t find the leather there or have already used it in some way before, then north of the monastery under a white awning you can find a locked chest with an easy difficulty lock. It stands directly opposite the entrance to the stables. Inside it you will find cow skin.




Find mint (4)
Mint can be found in the small monastery Forest Garden, located in the southeastern part of the location. You need to go through the gate east of the entrance to the hospital, and you will find yourself in a kind of economic territory with barns and beds. Examine the latter to find mint.



Find sage (4)
Note that with a high probability you can find it right in the infirmary, since it lies in large quantities in one of the unlocked wooden chests, standing next to the stone column (see screenshots below).



Plus, sage grows in the same garden as mint – you just need to check out the other beds. The screenshots below show the exact location of the flower you need (it has a purple oblong tip).


Important:To create aromatic oil, you will also need 3 chamomile and 1 valerian, so do not forget to collect them in the same Forest Garden – they grow in the beds east of the sage. The game will inform you about these ingredients only after receiving the recipe near the alchemy workbench. Let us add that mint is not needed at all to make this liquid. You will use it only at the very end, when you need to decorate the mask.
Find a recipe for aromatic oil
Now head to the library located in the southern part of the monastery. You can get here through the door in the east. The entrance is located near two staircases. Once inside the desired room, go to the southwesternmost book stand and read the book lying on it. You need to scroll through all the pages to the end.




Note: Note that you can also chat with Librarian Crispin here. If you pass the skill check, you can ask him where to look for the ingredients for the oil (useful if you haven't found them yet).


Make aromatic oil
Having obtained all the necessary ingredients, return to the hospital where the patients and Albicus are located, and then go to the far southern room, in which there is an alchemy table, and interact with the latter. Open the book and find the recipe for Volatile Oil. Here you will see that it requires 3 chamomile, 1 sage and 1 valerian to make it. Again, all this can be found in the Forest Garden.




Now start cooking the butter. To do this, follow these steps:
- As a base, take the oil on the top left shelf (second jug from the right).
- Now take 3 handfuls of chamomile and throw them into the cauldron with oil. Next, lower the pot to the fire, turn the hourglass over and start using the bellows to bring the oil to a boil. When the sand in the watch runs out, turn it over again – a total of 3 times. Then raise the boiler again.
- Take 1 handful of sage and place it in a mortar and then crush it with a pestle. Throw the resulting powder into the cauldron.
- Lower the cauldron again, turn the hourglass and use the bellows, causing the oil to boil for 1 turn. Then lift the cauldron.
- Grind 1 handful of valerian in a mortar and pestle and also add to the cauldron.
- At the end, take the bottle from the bottom left shelf and pour the resulting liquid into it.








If you did everything correctly, you should receive Fragrance Oil.
Make a Plague Suit
After making the potion, turn the camera to the right and interact with the table on the right (the inscription “Craft a plague mask” should appear in the lower right corner if you have all the necessary ingredients). Select mint, sage, cowhide (or pigskin), scented oil and bast rope from your inventory, then craft a Plague Hood.


This will end the quest, and you unlock the secret trophy “God protects those who are careful.” Now you can take on the task “Mute Witnesses” by going to explore the crypt.
