FINAL FANTASY XV - The Real Key To Solving Castlemark Tower Cube Puzzle

  • 7 years ago
This is the hardest part of the Castlemark Tower Sidequest and leads you to the main boss of the dungeon.

When you come out the bottom of a tower and the new map is square-ish with cube panels on the floor in each of the four corners, look for one of these floor cubes that you can interact with and follow where it takes you. It should lead you to a lower level battle with flans and Red Giants. After you defeat them all, look for the cube panel on the floor to bring you back up to the top courtyard with the four cube floor corners.

Now, you should be able to interact with another of the four corners' floors and you should see a checkmark where you descended previously. Continue to repeat this process until you have completed all four corners and their corresponding "fights in the basement" and be ready to fight 3 red giants and a medusa all at once!

If you hit a "dead end" on one of the cube routes, you may not unlock the next piece. Repeat the last part and check you map often to make sure you are exploring new paths (there will be forks along a couple of the routes so you may need to try an alternate path to get you to the fight at the end of the route). The first moments of this video discuss this issue which has stumped many FF fans!

The 4th and final route (in the SW / Bottom left) corner of the courtyard map will take you to the final boss of the dungeon - Jabbernock. He is easier than the 3 red giants / medusa fights in my opinion :)
