Upon entering the library, it is important not to enter the shop right away. Assuming you teleported in, the shop will be the room directly to your left. Instead, transform into Wolf and travel to the right until you reach a room with a large staircase and Book enemies flying about. Execute a [[Book Jump]] to reach a higher ledge to the upper left of this room that leads to a room containing the Faerie Card Relic. Do not enable the Relic right away.

Now, head back to the Shop and prepare to execute the Shop Glitch. Under normal circumstances, you cannot access your equipment while in the Shop. However, it is possible to trigger a glitch the first time you enter the Shop if you have certain items. One of these items is the Faerie Card Relic:

# Return to the Sell gem menu (note that you still have Garnets to sell, indicating that the glitch was successful)

# Sell at least 102 Garnets, which will show as E3 in the menu (thanks to an [[integer underflow]] that occurred when you sold the Garnet you had equipped, you now have 255 Garnets in your inventory)

Now that you have enough Gold to do so, purchase 1 Manna Prism, 2 Buffalo Stars, and the Duplicator. Don't forget to equip the Duplicator, Manna Prism, and Buffalo Star. With the Duplicator, you can now use consumable items an infinite number of times.

The Castle Keep section is the same section as from the Prologue with Richter, except now the staircase has fallen into ruin, leaving a gap you must fly over to enter the section where you will encounter the fight with Richter. During a normal playthrough of the game, you are expected to have the Holy Glasses at this point if you wish to be able to proceed to the Inverted Castle. In this category, however, the fastest routes all involve executing a glitch known as [[Richter Skip]] to avoid this check and proceed on to the Inverted Castle anyway.

There are two methods of performing [[Richter Skip]], and the faster method involves using a very precise jump at the top of the stairs while in Wolf form to jump over an invisible area that would normally trigger the camera to lock on to the hallway leading to the throne room. If you can avoid touching this invisible area, the camera will still be able to freely move about, allowing you to see clouds in an area of the ceiling that would ordinally be off-screen. This is your visual cue that the glitch has succeeded, and proceeding to the throne room will cause you to skip the cutscene and fight with Richter entirely and move on to the Inverted Castle.
