Coroa de Sonoite

- Found in Farron Keep, on a corpse lying under a white birch in a stretch of murky water to the left of the main gate and the Keep Ruins bonfire. The area is guarded by a Great Crab. - If the player befriended the Giant Archer of the Undead Settlement, he will fire greatarrows at any enemies near the birch, including the Great Crab. Each arrow will automatically stagger the crab for a free riposte, making it significantly easier to deal with.
