Xenoblade Chronicles X: Definitive Edition Guide | How To Unlock and Use Mechanical Field Skill

The Mechanical Field skill is one of the most important skills in Xenoblade Chronicles X: Definitive Edition! You may have seen those annoying treasure chests that you can't open no matter how hard you try. Well, mastering the Mechanical Field skill is the key to getting them. You can get the Mechanical Field Skill by following this guide.

The First Puzzle: The Ichor of the Quiet Lady

The lake in the Primordia region, west of FN Site 120 and south of FN Site 118, is what "Riddle behind rock at a primal lake, quiet lady's ichor thy lust will slake" refers to. Yelina, the locked-up level 34 tyrant monster, owns the quiet lady's ichor. 

To find her, go west of FN Site 120 to the huge stone arch that goes out over the water. Once you're under it, Yelina, who looks like a spider, will come down from the arch to fight you. Get her outside to finish this puzzle.

The Second Riddle: Deep into the Skies

The phrase "Soar deep into the skies and seek the forgotten land's ultimate peak" refers to a mountain peak in Oblivia that is a little east of Forum Site 315. For your scales to reach it, you need to unlock the flight module. 

To reach the highest point in the area, fly as high as you can. If you get that item, you can use it to open the sign for the scenic viewpoint on Mount Edge Peak. That name isn't very creative.

The Third Riddle: Elevated Corn

"Take this raised corn to hand atop the peaks of a delusional land" is the last and worst riddle. The peaks being talked about here are in the Delusion Mountains, which are west of Sylveum. 

More specifically, they are the North Summit of the Delusion. From FN Site 416, you can fly up to get there. You need to get these four Pale Maze items. 

I think they only spawn at night because I couldn't find them during the day. Make sure you change the time. I quickly traveled to the landmark at the Delusion's North Summit and then went east along this path, looping back up to get the items. I went back quickly to get the items again until I found four Pale Maze.

The Fourth Riddle: Suburban Glory

Once all three puzzles are solved, the main mission will add a fourth puzzle: "In Suburban Glory, as the sun goes down, the suffering speak of what is to come".

Suburban Glory is the name of the neighborhood in New LA, and "Sunset" is the name of Sundown. The Water Purification Plant is the closest place you can get to quickly. 

Solen is just southwest of it at Sundown, which is around 5:30 in the game. Talk to him to finish the quest and get the Mechanical Field skill.

You can now open that big box outside of Blade Headquarters and any other treasure you find in the mechanical field.
