This particular collectible Destiny 2 Bound Manacle is connected with the Essence of Insanity and, so does the Love and Death grenade launcher. This heavy weapon was recently reissued at current Power levels, so it’s actually usable and worth farming again.
In order to help you find the Bound Manacle more easily, we’ve articulated a quick guide showing exactly where to find the Gatehouse.
How to find the Gatehouse
The Gatehouse won’t be hard to locate into the Hellmouth, if you’ve done any other Essences, you’re probably visited through it a couple of times.
As you reach the Sorrow’s Harbor landing zone, head southwest and hang a right, further take the nearest entrance to the Hellmouth.
You should see a group of Acolytes, move further to find another group of Acolytes in a room filled with spires, and then come to a more ornate chamber.
You’ve arrived! Provided you have the Essence of Insanity on your, inside you’ll find a yellow-bar Hive Knight with a fancy name.
Kill him and you’ll automatically collect the Bound Manacle. We discovered this by chance while exploring, so we weren’t able to replicate it for the GIF above, so just trust us that the Knight will be there.
Voila! Your Essence of Insanity is ready to go and the Love and Death grenade launcher awaits. It’s especially worth grinding this Essence, as grenade launchers are still top-tier for DPS, and Love and Death can roll with rare and potent perk combinations.
