Once you have the Soul of Bat, leave the Library as quickly as possible and make your way to the Outer Wall. The easier method is to teleport back near the shop using a Library Card, then proceed to Wing Smash your way to the Outer Wall. The much more difficult method is to execute the [[Wolf Floor Clip]]. Whichever method you execute, once you find yourself at the Outer Wall, take the next section beginselevator to the top, then continue upward until you reach the entrance to the Clock Tower.

== Clock Tower & Richter Skip ==At the start of this section, you will transform into Bat and Wing Smash your way across the large chasm. This next section is filled with spawning Medusa heads and Harpies throwing knives at you, so precise movement is critical to avoid getting hit while you make your way to the section with the Sword Lords. Navigate between the broken stairs and make your way toward Karasuman. After killing Karasuman with Buffalo Stars, move left into the Castle Keep section. 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. ==Inverted Castle == == Second Castle Relic Skip & Final Battle ==
