There needs to be some clarification about the Destiny 2 Empty Grief weekly challenges. First, you must complete the Severe (Grief), a seasonal task, using only Void, Kinetic, or Stasis weapons. Despite using the correct weapon elements and subclass, players often find the challenge is still ongoing.
It could be a bug. It’s kind of. This is what you should do to get season rank XP and complete the weekly Empty Grief Challenge. You might want to search for Calus Bobbleheads if you are aiming to earn the Season of the Haunted triumph stamp. If you’re starting, you may also need to learn Opulent keys and how to open chests for loot.
Destiny 2: Empty Grief: How do you complete the challenge
Although it’s difficult to determine if this is intentional, some players need to complete the challenge because they are taking the scythe from the final boss encounter. The Solar weapon counts the scythe as your challenge. Therefore, if the final boss summons the scythe, ignore it. Even though Eris might want you to, you don’t have to pick up the scythe to advance the fight.
You can complete the challenge by equipping your Void subclass and any Void, Kinetic, or Stasis weapon. While I am still determining how this will affect the challenge, you should ensure you don’t use Solar or Arc finishers when you do bounties.
