The "most stupid follower of ChAoS" is a special victory condition available only to the Chaos Knight class. This ending is achieved by completing the standard Close the Chaos Gate victory conditions with a Chaos Knight of chaotic alignment. In this case, rather than exiting the Drakalor Chain and returning a victorious hero, the character's existence is immediately snuffed out. Thus players who choose this ending will have no opportunity to return to prior locations or cure corruptions to improve their final score.
A death message accompanying this ending is: "committed to the ultimate sacrifice by closing the Chaos Gate thusly ending his/her existence on level 50 of the caverns of chaos."
