Lecture Building 1F

From the Grand Cathedral, make your way through the area where you fought the two Hunters and two Executioners. Head towards the church that leads to Yahar'gul, Unseen Village. As you approach the doorway, the Lesser Amygdala will grab you. Instead of avoiding it, allow it to grab you to reach Lecture Building 1F.

Upon arrival, light the lamp. Cross the hall and enter the first doorway, followed by another, to reach the first lecture hall. A Scholar will fall from above.

After the Scholar falls, grab the Lecture Theatre Key and the Student Set from the room. Exit through the other side into the circular room next door.

In the circular room, you will find Madman's Knowledge x2. Be aware that another Scholar will fall from above.

Cross the hall, ignoring the glowing door for now, and enter the first room on this side to find a chest containing Red Jelly x2. These are useful for Chalice Dungeons.

Return to the side of the hall with the glowing door. Use the Lecture Theatre Key to enter the room. This room is filled with Scholars. Back up and let them clump together before dashing in to attack, then retreat.

Once all enemies in the lecture hall are defeated, exit through the opposite door. Pick up the Augur of Ebrietas.

Return to the glowing door and enter it to proceed to the Nightmare Frontier.
