Prophecy of Madness is a level 70 five player skirmish. There are three stages to the skirmish that are measured in Bronze, Silver, and Gold. How quickly you complete each stage gives you one of the three ratings. Completing a minimum of two gold stages and a high Silver is needed to get an overall Gold rating which will then unlock this achievement. This variant will have you fighting Demons while running to the wards for cleansing and strengthening.
