The Equilibrium dungeon in Destiny 2 brings a slew of secrets, but it’s not all just Star Wars weapons and lightsaber crystals. As usual, Bungie hid some collectibles in different points in the dungeon, which help if you’re looking to get the Heirloom Exotic or just want another fashion option.
Finding all collectibles grants you the Praxic Drape shader, which is the base tincture used for the dungeon’s Jedi-inspired armor, and it also bumps your odds of getting the Heirloom Exotic. Here are the locations of all three of them in the Equilibrium dungeon. Don’t forget to pick up the dungeon’s secret chests while you’re at it.
First collectible: On the ship after the first encounter

Clear the first encounter in the dungeon and keep going through the Harvester. After the pilot turns on the NLS drive and makes your screen shake, you’ll come up on a small warehouse full of enemies and a semi-open area that lets you look into space. From here, drop down at the end of the hallway and find the first Equilibrium collectible on the ground, below the entrance.
Second collectible: After the second encounter, in the hangar

After taking down Harrow, Dredgen Apprentice, you’ll crawl out of a duct into an open hangar with ships in the distance and a few enemies near you, including a Behemoth. Don’t follow the correct path on the right, which leads you upward and into an open tube. Instead, go to the ships on the left side of the room, where the snipers are. There’s a small crate behind the second ship, and you’ll find the collectible inside it.
Third collectible: Below the tank after the second encounter

Continue and you’ll find an area with two Behemoths and an inactive tank. Jump below the tank as usual and take the first duct on your right to find the last Equilibrium collectible on the ground, in a short hallway blocked by some junk. The item itself may be difficult to see, but the Interact prompt gives it away more easily.
Once you’ve found all three collectibles, don’t forget to claim the Listen In triumph, which grants a boost to Heirloom’s drop rate. It doesn’t do anything for your odds of getting the Dark Crystal for your Praxic Blade, however.
Outside of the award, you also get the Praxic Drape shader, used in the dungeon’s base armor. The brown has a slight leathery texture that shows up when using it in other gear, and one of the beige tones also brings a cloth texture. It may not go well with every armor piece, especially some of the bulkier ones. But hey, there’s no such thing as too many shaders. At least until you have to scroll all the way to the back to find new ones, anyway.
