Last update: 24 January 2018
The stone circles that also appeared in the core game, can be found be in the DLC as well. There are only two such locations on the whole map; their riddles are solved by finding and matching constellations on the nightsky. Every stone circle will yield one skill point.
Ankh Stone Circle
In order to match this one, you have to turn the stars a bit left and then slide them to the right. Go past the black shape of a mountain - right next to it, to the right, there's the spot you're looking for.
Sobek Stone Circle
When the star map shows up, turn the constellation 180 degrees. Slide it to the left and place it where the small starcluster is.
