Lecture Hall Skip

From SpeedSouls - A Dark Souls Speedrunning Wiki

The Lecture Hall Skip is a skip in Bloodborne that allows the player to bypass the second floor of the Lecture Hall in order to reach the Nightmare Frontier (Amygdala) faster.

The skip involves using the geography of a wall pillar and the baseboards of the flooring to boost your jump to clear a balcony railing. The skip is located in the room immediately left of the Lantern on the second floor. The player will open a door and proceed to the corner of the room in which they are able to do the skip.
