The "Discipline" Add-on Range lets Survivors afflicted by Madness have a Fake Red Stain.
The Doctor's Red Stain will be removed from him and put directly onto the afflicted Survivor, highlighting them for The Doctor (very useful in the cornfields of Coldwind Farm) and making it immensely difficult for the afflicted Survivors to judge the distance The Doctor is from them (making it more difficult to juke a lunge attack) or the direction he's coming from (around walls for example).
There are currently 3 types of "Discipline" Add-ons:
|"Discipline" - Class II||（附加品叙述未加入Template:Add-on desc）|
|"Discipline" - Class III||（附加品叙述未加入Template:Add-on desc）|
|"Discipline" - Carter's Notes||（附加品叙述未加入Template:Add-on desc）|
