Manual

The Manual is an item Ralsei gives to Kris after they complete or decline the Dummy tutorial battle. It cannot be sold to shopkeepers.
If dropped while Ralsei is in the party, he initially assumes Kris dropped it by mistake and returns it. If Kris tosses the Manual a second time while Ralsei is present, he promises to make a better manual next time.
If kept, it disappears from the inventory in Chapter 2, and reappears on a nightstand in Kris's room within Ralsei's castle. If the manual was thrown away in Chapter 1, a trash can appears on the nightstand instead.
== Additional Uses ==
* It can be used in battle against Rudinns to make them tired, allowing Ralsei to spare them with his Pacify spell.
* It can be read to Hathy, who "[listens] politely," but with no other effect.
* It can be read to Clover, who becomes "sentimental" and adds 50% to her Mercy meter, allowing her to be spared sooner.
== Flavor Text ==
* (You tried to read the manual, but it was so dense it made your head spin...) [When used]
* (You drop the manual on the floor with a resounding thud.) [When dropped]
** [If Ralsei is present]
** [Ralsei] Hey, Kris. What are you doing...?
** [Ralsei] Oh no! Is that the manual?
** [Ralsei] Looks like you accidentally dropped it...
** [Ralsei] Here you go, Kris! You don't wanna lose that!
** (You got the manual.) (Again.)
* (You tossed the Manual hard.) (Its pages scatter in the wind.) [When dropped a second time]
** [If Ralsei is present]
** [Ralsei] ..............
** [Ralsei] Umm... Th-that's OK, Kris! I can always...
** [Ralsei] I'll just make a better one next time!
* [Ralsei] ... [When dropped a third time if Ralsei is present; unused as the manual does not return the second time]
== Trivia ==
* In the game files, there are images for pages of the manual that went unused.
** In the UNDERTALE 6th Anniversary stream, Toby Fox explains that he had considered making the Manual readable, but scrapped the idea. He also mentions that Temmie Chang recreated a physical version of the Manual.
* There are a few instances where Ralsei leaves the party and the Manual can be dropped without him knowing.
** Immediately after Lancer runs off to Card Castle and Ralsei chases after.
** After defeating King, but before closing the Eastern Fountain.
** Dropping the Manual while Ralsei isn't in the party will not make the trash can appear in Kris's room. 
* If Kris drops the Manual in the hidden area in the Forest, Ralsei's dialogue still triggers.
* It can be removed from the inventory with the Glowshard glitch if it is in the second or third slot. This is not considered dropped in Chapter 2, as the Manual still appears in Kris's room.
* The manual is the only non-key item that is not carried over to Chapter 2.
