Willow the Wisp of Smoke is an achievement that requires the player to light a willow log fire on top of the Lumbridge Castle's gatehouse, east side (front) of the castle, not behind the castle.


  • This achievement used to be a task prior to the release of the Achievements System on 18 April 2017.
  • The achievement name is a play-on-words of "willow" and "will-o'-the-wisp".
