Tower of Remembrance - Degradation is a stage featured in Soulcalibur IV, notably used by Algol. This stage is similar to Tower of Remembrance - Encounter, except this stage has been divided into two by color: the blue side which may refer to Soul Calibur, and the red side which may refer to Soul Edge, and also the giant rotten eye is missing. The characters that fight against Algol in their final stage face him off in this stage. The final floor when ascending in the Tower of Lost Souls features a stronger Algol and takes place at this stage. The battle music during this event is changed.
