  • The Mystical Monument is a building which primarily serves as a decoration, but does provide some small bonuses.
  • For each upgrade level, instead of having a set cost of resources, a choice is given of four different options to pay to upgrade it, with each being a significant amount of a resource or other items.
    • The options for which resources can be used for the upgrade can be re-rolled at the cost of 20 diamonds.
  • The Mystical Monument has 300 levels.
  • It is located in the water, to the right of the beach on your home island.
