How To Craft A Plague Mask In Kingdom Come: Deliverance 2 2025

Complete the Prevention quest in Mysteria Ecclesiae.

It's unclear whether crafting the plague mask in Kingdom Come: Deliverance 2's new Mysteria Ecclesiae DLC is necessary, but I know I wouldn't want to delve into a plague crypt without a little protection. If you're mindful of the potential consequences of exposing yourself to plague and spreading it around, you'll want to do as the physicians suggest and craft yourself a plague mask as part of the Prevention quest.

The bad news is that Sedletz Monastery has gone into lockdown, its monks into seclusion, and the abbot has ordered you to stay put in the infirmary, and absolutely not go sneaking about investigating the source of the plague. But sneaking about you will go if you want to grab the necessary materials for the plague mask, so make sure to avoid guards and save often.

If one does spot you, either try to sprint into a safe, non-private area, or simply ask them to take you back to the infirmary by replying. This will save you getting dragged before the abbot and, if you're like me, having all those golden crucifixes you stole taken away.

Your first step in crafting the mask is gathering some herbs, which you can do in the Woodland Garden in the southeast of the map, by Herbalist Joachim's hut. You can't purchase anything from Joachim, so you'll have to pick these yourself from the garden. You'll want:

While you only need the mint according to the objective, you'll need the chamomile, sage, and valerian to brew the Essential Oil once you have its recipe, so grabbing this now will save you coming back later.

Next up is the oil recipe. You can get this by reading the book on the lectern in the southwest corner of the library—you will have visited here before while investigating the plague victims.

If you speak to Crispin, the librarian, you'll have to convince him why you're breaking quarantine, so it's better to just find and read the book if possible. Once read, you'll automatically get the Essential Oil recipe in your inventory.

Now you need rope and leather, or in this case, Flax Rope and Pig Skin. You can find both of these at the building site just to the south of the main entrance to the monastery chapel, in the west of the map—just be careful of all the guards wandering around and make sure they don't catch you.
