One of the quests in Destiny 2: Shadowkeep, "The Essence of Failure", consists of several steps, by completing which you will receive the Lightning Logic automatic rifle. However, the condition for obtaining is the subject Prisoner Bond, located in the location of one of the very first missions of the story campaign.
Where to find Lunar battlefields
First, you need to travel south from Sorrow's Harbor, where, looking south, you will find yourself on a red bridge.
Walk across the bridge and go around the path to enter the Lunar Battlefields.
Where to Find the Bond of the Prisoner
After leaving the bridge, you will notice a path going up the slope slightly to the right. The road has a mesh bar along the orange lane so you know you are heading in the right direction.
Follow the path and eventually you will be taken to the lunar base.
If you tracked the quest, a marker will appear on the nearest building to the right.
Go to the roof of this building and activate a hint.
This will give you the item Prisoner Bond.
Essence of Failure quest steps
The problem is this. Game Destiny 2. Platform PS4. No cross-save and account linkage. The plot in Shadowkeep has stopped. Eris Morn gave a task with some essence. Essenzi. had to be charged by fulfilling three contracts. Executed. Loaded. The essence is gone. Morne does not give new tasks and does not say anything. I ran on the moon. Another essence dropped from some event. It was required to charge with the Horned Wreath. Found the wreath. Loaded. Morne is silent. Nothing happens. Essence hangs in the assignments and writes, talk to Morn. There were recommendations to look for the missing task from the postmaster or activate the essence on the alchemy table. The postmaster is empty. The table is not active. I would have started the lunar campaign first, but there is no such trigger. If anyone knows what's going on, then unsubscribe. Thanks!
