The Shrine of Challenge is not available until the player unlocks it by entering [[Qi's Walnut Room|Mr. Qi's room]] on [[Ginger Island]] and completing the "[[Quests#Danger In The Deep|Danger In The Deep]]" quest.
Thereafter, the Shrine of Challenge is located on floor 120 of the Mines. It acts as a toggle switch, alternating the strengths of The Mines enemies between normal levels and difficult"dangerous" levels. ''The toggle does not change strength levels until the following day.''
While the difficult level dangerous setting is active, [[Radioactive Node]]s can be found in the Mines, from which [[Radioactive Ore]] can be obtained.
