The Top 10 Most Challenging Achievements: Xbox One

08. Dragon Age Inquisition: Stargazer (15G) Unlock15 astrariums in a single playthrough

The newest entry in the Dragon Age series is fully worthy of the well-established reputation as a deep and entertaining story and game play experience, once again delivering a massive amount of entertainment that far exceeds the paltry price of admission.

That said, among its many entertaining and challenging Achievements is one that stands out head-and-shoulders above the rest for a number of reasons, not the least of which is the fact that when you stumble upon the mechanism around which it is built it is a surprise in and of itself.

What is even more surprising is the complexity of the puzzles that make up the set of mechanisms - because working out the proper sequence to connect the lines is incredibly challenging and fun - even for the least complex of the puzzles!

Actually it is fair to describe the entire process as a puzzle within a puzzle - since the astraria are hidden throughout the lands and so must be found before you can begin to think about solving their starchart puzzles!

We said puzzle within a puzzle because in addition to the starchart puzzles inside of each you will find that solving any one of the puzzles will cause the astrariums to point you towards the next one in the sequence!

Check out the video embedded above for help with the more complicated of the puzzles - as help you will likely need!
