Agony seat

Agony seats were a form of torture created by the Kaleds. Davros used one on the Fourth Doctor, Harry, and Sarah Jane to extract information about all future Dalek victories and defeats. (TV: Genesis of the Daleks)

The Seventh Doctor was placed in an agony seat in order to extract all of his victories so the Daleks could undo them. (AUDIO: Daleks Among Us)
