The Novtumber Festival is a Treasure Hunter promotion that was originally planned for August 2015 under the name Harvest Festival. For unknown reasons this Treasure Hunter promotion was cancelled and later renamed to Novtumber Festival and rescheduled becoming active between 19 November 2015 and 23 November 2015.
During the Festival, players could win Novtumber Festival seeds, which could be planted anywhere a fire can be lit. After about 20 seconds, these plants grew fully, and could be harvested for either a Novtumber Festival produce or, rarely, a Novtumber Festival perfect produce. Both types of produce could either be offered to the gods for Prayer experience or returned to the earth for Farming experience.
