Kingdom Come Deliverance 2 Mysteria Ecclesiae: Complete Foreseeing Evil Walkthrough

The Mysteria Ecclesiae DLC for Kingdom Come: Deliverance 2 introduces several missable tasks that can permanently affect your playthrough. Among these, “Foreseeing Evil” stands out as a crucial yet easily overlooked objective that requires stealth, timing, and careful planning to complete successfully. Here’s everything you need to know about completing this mysterious library quest.

Kingdom Come Deliverance 2 Facts: Foreseeing Evil Task

Understanding the Foreseeing Evil Task

Foreseeing Evil is one of the optional tasks available during the Mysteria Ecclesiae expansion, specifically triggering at the beginning of the Silent Witnesses quest. What makes this task particularly tricky is its timing—you must complete it before investigating the monastery crypt, and the monastery is on lockdown with guards patrolling everywhere.

The task involves helping Librarian Crispin protect himself from the mysterious illness spreading throughout Sedletz Monastery. Your mission: gather specific herbs from the herbalist’s garden and deliver them safely to the library without alerting the knights.

Step-by-Step: Completing Foreseeing Evil

Trigger the Quest: During the Silent Witnesses quest (after completing Anamnesis), navigate to the monastery library and speak with Librarian Crispin. When dialogue options appear, avoid using skill checks or choose the non-skillcheck option: “I’ll help you to protect yourself from the illness.” This triggers the Foreseeing Evil task.

Plan Your Route: The monastery is on lockdown following the Anamnesis quest. Guards patrol the grounds and will escort you back to the infirmary if caught—voiding the “Quiet as a Church Mouse” achievement. Study guard patrol patterns and wait for them to move before proceeding.

Locate the Herbalist’s Garden: Head to the herbalist’s garden within the monastery grounds. You’ll need to gather two specific herbs: Mint leaves and Sage plants. Both are clearly identifiable in the garden area, though you’ll need to crouch and move carefully to avoid detection.

Return to the Library: Once you’ve collected both Mint and Sage, carefully make your way back to the library using the same stealth tactics. A viable route typically involves staying close to building walls and timing your movements between guard patrols.

Complete the Delivery: Speak with Librarian Crispin again and hand over the herbs. He’ll provide information about aromatic oil, which directly assists with the Prevention task—another important objective in the DLC.

Critical Timing & Missable Content Warning

The “missable” designation isn’t just for achievement hunters—failing to complete Foreseeing Evil before progressing too far in the main DLC questline can permanently lock you out. This task must be started during the Silent Witnesses quest and completed before investigating the crypt for the main storyline.

If you’re aiming for 100% completion or the “Do Good to All People” achievement, Foreseeing Evil counts toward the total number of helpful acts required. Players have reported needing to complete multiple tasks including Foreseeing Evil, Maddening Pain, Anamnesis, and Our Old Bread to unlock this achievement.

Stealth Tips for the Lockdown Phase

The monastery lockdown creates one of the most challenging stealth scenarios in the entire game. Guards are positioned at key intersections and patrol unpredictably. To maintain stealth, crouch-walk along building perimeters where shadows are deepest, save frequently before attempting risky movements, and wait patiently for guards to complete their patrol loops before moving.

If a guard spots you, they’ll escort you back to the infirmary, resetting your progress. While this doesn’t fail the quest immediately, repeated captures waste valuable time and increase frustration. Players pursuing the “Quiet as a Church Mouse” achievement must avoid capture entirely throughout the DLC.

Connecting to Other Tasks

Foreseeing Evil doesn’t exist in isolation—it connects directly to the Prevention task, which requires you to craft a protective mask against the monastery plague. The aromatic oil information Crispin provides becomes essential for completing Prevention successfully.

Additionally, while in the library, interact with the cat in the back left corner near the last bookshelf if you see the “Kitty kitty…” prompt. This counts toward the “Feline Affection” achievement, requiring multiple interactions throughout the DLC.

Why This Task Matters for Story Immersion

Beyond achievements and completion percentages, Foreseeing Evil adds meaningful context to the Mysteria Ecclesiae narrative. The DLC explores medieval medicine in the context of a mysterious infection, and helping Crispin protect himself demonstrates Henry’s growing understanding of the crisis unfolding at Sedletz Monastery.

The task showcases the historically accurate medical practices of the era, where herbs like mint and sage were genuinely believed to offer protection against diseases—knowledge that Warhorse Studios meticulously researched for authenticity.

Mysteria Ecclesiae: The Final DLC Chapter

Mysteria Ecclesiae is the final piece of DLC for Kingdom Come: Deliverance 2, offering an estimated 12+ hours of gameplay. The expansion focuses on uncovering dark secrets within Sedletz Monastery, where faith and fear collide during a quarantine.

To access the DLC, you must reach the Kuttenberg region during Main Quest 13: “The Sword and the Quill.” Look for Peter of Pisek in Suchdol to begin your investigation. For more information, visit the official Warhorse Studios website.
