The Sacred Sites update is inbound. If everything goes according to plan it will release tomorrow. This update will sometimes spawn special floors that are dangerous, mysterious, and/or rewarding. These floors are: Sophie's Sanctum, The Lake of Cleansing, The Forge of Destiny, The Labyrinth, The Labyrinthine Library, and the Arbiter Grounds.
Most of these floors tie in with one of the three deities in the game. Making their presence more prominent, and putting more weight on your decision what god to follow.
Many of these Sacred Sites will be hard to get into, but the rewards will worth it.
If you cannot wait to explore these new sites you could help us by switching to the unstable branch. We've just uploaded the latest build to that branch for you to test out... If you dare!
To switch, simply right click Unexplored in your Steam Library, select properties, and go the to Updates tab page.
And you would be helping us making sure everything works as intended before we roll out the update to everybody...
