Where to find the sphinx in "A Game of Wits" (both times!)
Dragon's Dogma 2: How To Solve All 10 Sphinx Riddles
by Diego Nicolás Argüello
The Sphinx Riddles are one of the most complex challenges in Dragon's Dogma 2, but are well worth the time to solve. Although the hunt for the Sphinx Riddles (“A Game of Wits”) is an ordeal that prevents you from completing ten complicated missions, you will reap great rewards.
Before we begin, some good and bad news. The good news is that you can start "A Game of Wits" at any point in your playthrough. The bad news is that completing all the Sphinx puzzles can be a long and arduous process, especially if you approach the quest at a low level.
