The hourglass chamber is a secret room located right above the Hiisi Base hidden shop, either in the East or West walls of the biome. Inside there is an hourglass containing a small pool of Blood in the bottom which can be filled with different liquids to activate beneficial events.
Currently there are 3 different ways to activate the hourglass, but only one can be attained per game. If the hourglass is damaged or broken prior to activating one of these effects, it will trigger an Earthquake
If you fill the hourglass with enough blood, all of it will turn into about 1,000 worth of gold powder. You can then collect it by breaking the hourglass, becoming oiled, or teleporting into the bottom of the hourglass.
If you fill the hourglass with about 70% of a regular flask of Teleportatium or Unstable Teleportatium, a portal will appear above the hourglass. The portal will take you to an eye-shaped room that contains 8 free Spells, chosen at random from all unlocked spells.
