Started September 27 2009 and ended October 6 2009. A list of 50 numbers was provided, and guilds searched the lands of Estiah to find items with prices equal to those numbers. Every correct answer was worth one point, every wrong answer deducted a point, and no answer had no effect on points. The winning guild (Free Waffles) got 100 Phoenix Feathers, and second place (Torch The Bridge) got 40 Feathers.
