This is the first errand you’ll get as soon as you start the game. First, Rost will tell you to check out the elderly outcast Odd Grata and hunt for wildlife to supply her with food. They’re quite common but they’re usually hard to spot and hit without scan the area using your Focus and tagging them. Follow the marker to Odd Grata and hunt wildlife along the way to get enough meat for her.
After talking to her, you then need to head to the Overlook Climb to recover her prayer bead. Head to the location and take out the three watchers lurking nearby. To reach the overlook, you have to climb using the climbing holds on the side of the rock cliff. Be careful not to miss your jump!
Once you reach the overlook, examine the supply crate by the bench to retrieve the prayer beads. From here, you can fast travel to the nearest campfire to Odd Grata’s location. Otherwise, you can rappel down the branch and walk all the way there. Deliver the prayer beads to Odd Grata to complete the errand.
