Mystical Buildings: Solid Foundations is a popular mod that offers a wide variety of custom buildings, which can be built and used daily or at custom intervals.

In addition to that, the mod offers an option to set individual cooldown (in days) for each building, which allows you to use them all with ease.

The addon also includes a Quizzical Statue, which can be used to earn rewards. A lot of new buildings are also added to the game, including a statue of Greed, a not-so-stable mineshaft, an orb of reflection, and a phantom clock.
