A hidden room will appear connected to the Library.\r<br>- The hidden room contains a locked Grate. Use two keys to open it.\r<br>- Inside the Oubliette, you will fight Blobulord, and you can find the Old Crest. You will need this to enter the second secret level.\r<br>\r<br>To access the Abbey of the True Gun:\r<br>- Take the Old Crest from the Oubliette\r<br>- Navigate the 2nd level without taking damage (Old Crest is an armor item that sits on top of the stack - any hit will break it first)\r<br>- Find the Altar and place the Old Crest on it - this will reveal the passage to the Abbey of the True Gun.\r<br>- In the Abbey, you will face the Old King.
