Once you’re through the story campaign of
Each week, you can help Eris Morn dispel the phantoms of her dead fireteam by completing a short quest. This week, it’s Vell Tarlowe, a powerful Titan who was overwhelmed by Thralls and killed in the Hellmouth, during the team’s ill-fated attempt to destroy Crota. To get rid of the phantom, you’ll need to find Vell Tarlowe’s Titan mark.
To start the mission, talk to Eris. She’ll give you the Memory of Vell Tarlowe mission, which first requires you to replay a mission from the Shadowkeep story campaign. You can access that mission from the Director, and you don’t have to do anything special to complete the step–just finish the mission as normal.
Next, you’ll need to venture into Nightmare Hunts in order to gather the pieces of Vell’s mark. In order to find the pieces, you need to defeat enemies on the Hunts with melee strikes. Any enemies will do, and it doesn’t seem as though your melee ability has to be fully charged to make pieces of the mark drop from enemies. It also appears that roaming, melee-focused Super abilities, such as Hunters’ Arc Staff, can count as melee strikes.
You’ll need 25 pieces of Vell’s mark, but they won’t drop from every melee kill you execute. The good news is, they drop in batches of three, so you really only need to get nine drops to finish the mission. We managed to complete this step in two Nightmare Hunts, so it really does go quickly.
When you’re done, head to the Sanctuary on the moon and go through the portal to find Eris. Give her the mark to dispel Vell’s phantom and earn your Powerful drop from the nearby chest. You can also hang around and talk to Eris twice more to get a little more backstory about Vell Tarlowe and his role on Eris’s fireteam.
