A certain chest found in chapter 14 contains a bonus. However, you can reach it only after solving the puzzle. This page of our guide to Darksiders Genesis has a full solution to this puzzle. Solve it to open the passage to the cave with the chest.
To solve the puzzle, you must first reach the platform moving on the map. As you move along it, you will notice a shelf. A column with a blue button is standing next to it. Quickly jump on it and defeat opponents.
To activate the first part of the door, you have to activate the blue button and then jump to the lower floor.
When you go to the right side of the location, you will find two points where you can open a portal.
After opening it, jump into one of them and wait for your character to jump higher. You can't move the hero now.
When you reach the desired height, hit the button located on the right side of the wall. This will open the passage.
Inside the chest you will find Outlaw s Abyssal Armor Shard.
