It is acquired by recording writing on a wall in the Male Ward.
"The harder I try to escape, the further I get into this god awful place. Like fighting a tar pit. They've been torturing people in the basement, and by method. Written on the wall- "FINGERS FIRST. THEN BALLS. THEN TONGUE." Somebody's managing the torture, instructing them."
The writing on the wall refers to Richard Trager and his torture methods.
In Temple Gate Town Square, an Easter Egg of this method can be found written on one of the house's basement walls.
