How to Stack the Stones to Complete Maen Ceti¶

As with all cairn mysteries in the game, you can complete them in numerous different ways. However, some structures are more likely to yield stability than others. The key to this one is to place the largest rock horizontally, rather than vertically. It will then form a stable base for all the other rocks to be stacked on top.

In our case, we stacked only one stone vertically, and the rest horizontally. The combined structure only just passed the threshold, but it was stable enough to be reliable as a method to follow. You may find the last stone a little tricky to add, but if you pull downwards as you add it, you’ll be able to align it in a position without having to drop it directly on top of the other rocks. In this way you can gently place it once you know it’s stable.

Once you stacked the stones to the required height threshold, validate their position to complete the mystery.
