Overview
The Devil of the Reed Field is a target you must track across two back-to-back main quests in Chapter 3 of Crimson Desert: Nonhuman and Seed of Unease. Both quests lack clear map markers, which makes finding the Reed Devil's location confusing. This guide covers the entire tracking sequence from Grace Manor through to the final altar where the Dancing With the Devil boss fight begins.
Nonhuman Quest: Track the Devil
Go to the upper floor of Grace Manor and speak with the Servant NPC.
In the same room, observe the blue outlines representing a memory. View the memory called "Grace Manor."
Exit through the window and activate your lantern (L1 / LB) to reveal a yellow tracking line on the ground.
Follow the yellow line. You will encounter groups of enemies along the way. Defeat them and keep following the line.
The path leads to a hut. A cutscene plays when you arrive, showing the Reed Devil escaping.
Seed of Unease Quest: Follow the Devil to the Reed Field
After the hut cutscene, use your lantern again (L1 / LB) to pick up the yellow tracking line.
Head southwest from the hut toward a canyon.
Travel along the canyon road. The Reed Devil will appear alongside other enemies as you approach.
Damage the Reed Devil when he shows up. He will disappear after taking enough hits.
Continue along the linear canyon path, following the yellow lantern line. You can run past most of the spawning enemies; focus on hitting the Reed Devil whenever he materializes.
Make sure to heal with food items regularly. The Reed Devil hits hard even during these brief encounters.
Final Location: The Altar
Follow the canyon south until you reach a large open field.
Look for an altar in the middle of this field.
Inspect the small straw figure sitting on the altar.
This completes the Seed of Unease quest and triggers the Dancing With the Devil boss fight.
Tips
The lantern is your only navigation tool for these quests. If you lose track of the yellow line, toggle the lantern off and back on.
Bring plenty of healing supplies. The Reed Devil is strong, and the journey through the canyon is long with frequent enemy spawns.
You do not need to defeat every enemy group in the canyon. Prioritize hitting the Reed Devil when he appears and running past everything else.
The altar in the open field can be hard to spot. It sits roughly in the center of the southern field at the end of the canyon.
