How to access[ | ]

Notes[ | ]

• The Abbey always has a secret room containing Brother Albern and his chest. Breaking this chest gives Lies.
  • This secret room spawns separately from normal secret room spawns, meaning the player is more likely to discover multiple secret rooms on the Abbey than on any other floor, other than possibly Bullet Hell.
• This floor introduces Pews, strips of wood that act as indestructible obstacles which impede movement while allowing bullets to pass over them.

Trivia[ | ]

• Statues of Kaliber can be seen as decoration in the boss room.
• Paintings of the High Priest can be found throughout the floor.
  • In addition, paintings of the minions summoned in the boss fight against Interdimensional Horror are mysteriously found throughout the floor.
• The music that plays in the Abbey was originally used in Keep of the Lead Lord during the alpha.
