If anybody looked at the Trollspire Dungeon from above, they would be stunned to see over a hundred glowing golden rods with black lightning streaming around each and every single golden rod.
To those who were not knowledgeable in the art of formations and arrays, it would look like the golden rods had been placed in completely random positions.
However, to Array Masters and Formation Masters, they would be stunned by the sight of the current Trollspire Dungeon.
Why?
Because the entire Trollspire Dungeon had transformed into an array.
Every golden rod was what formed the array, and the name of this array is the Heaven Lock Array.
The Heaven Lock Array was one of the many arrays he obtained from the Central Library of the Underworld, and this array was an array that was designed for Tribulations.
The Heaven Lock Array is a high level array that was designed to protect an individual from a Tribulation, specifically, Lightning Tribulations.
