To complete Hornsent Grandam’s quest in Elden Ring’s Shadow of the Erdtree DLC, follow these steps:

  1. Locate Hornsent Grandam: You’ll find her in the Storeroom inside Belurat, Tower Settlement. The door to this area is initially locked and requires a specific key to unlock.
  2. Initial Encounter: Upon unlocking the door and meeting Hornsent Grandam for the first time, she will have some introductory dialogue, but there won’t be an immediate quest available.
  3. Defeat Divine Beast Dancing Lion: Progress through the DLC until you defeat the Divine Beast Dancing Lion boss. This boss fight rewards you with the Divine Beast Head.
  4. Return to Hornsent Grandam: After obtaining the Divine Beast Head as a reward, return to Hornsent Grandam while wearing the Divine Beast Head as your headpiece.
  5. Obtain Watchful Spirit: Speak to Hornsent Grandam while wearing the Divine Beast Head. She will then reward you with the Watchful Spirit spell.
  6. Reset the Zone: Travel to any Site of Grace and sit down to reset the zone.
  7. Talk to Hornsent Grandam Again: Return to Hornsent Grandam after resetting the zone. This time, she will give you the Scorpion Stew.
  8. Defeat Messmer the Impaler: Proceed with the DLC and defeat Messmer the Impaler at Shadow Keep.
  9. Final Interaction: Return to Hornsent Grandam once more after defeating Messmer the Impaler. At this point, you do not need to wear the Divine Beast Head again.
  10. Receive Gourmet Scorpion Stew: Hornsent Grandam will now reward you with the Gourmet Scorpion Stew.

Rewards:

  • Watchful Spirit: A spell obtained after the initial interaction wearing the Divine Beast Head.
  • Scorpion Stew: Received after the second interaction wearing the Divine Beast Head.
  • Gourmet Scorpion Stew: Obtained after the final interaction, no headpiece requirement.

Following these steps ensures you complete Hornsent Grandam’s quest in Elden Ring’s Shadow of the Erdtree DLC and receive all the rewards she has to offer. Keep in mind the specific interactions and the sequence of events to avoid missing any part of the questline.
