Y.E.E.T.U.S. Facility, A.K.A. YEETUSF or Yielding Eternal Extreme Tests Using Skill Facility, is actually a Citadel, because it has 14 floors. This is supposed to be in FToH Place 8. Difficulties of the floors: 1st floor: High Catastrophic 2nd floor: High Unreal 3rd floor: Very low nil 4th floor: Low Catastrophic 5th floor: High Horrific 6th floor (Break floor): Low Insane 7th floor: High Terrifying 8th floor (Bottom Half): Very Low Horrific 9th floor (Top Half): Mid Catastrophic 10th floor: High Unreal 11th floor (The Barrier: Gameplay N/A 12th floor: High Horrific 13th floor: Baseline Horrific (unless you have good eyes) 14th floor: High Nil 15th floor (Final): Low Nil
