Geirdriful can be found in the Hidden Chamber of Odin situated near Sindri's shop in the Foothills area. As with other chambers, the Magic Chisel is required to gain entry. Geirdriful is known for her aerial attacks and blinding moves, so maintaining a safe distance and using Atreus' arrows to disrupt her flight will be key. Blocking or evading her blinding attack will also help ensure victory.
