Dinraal's Scale

are items in.

Location and Uses
Scales can be collected from the dragon, Dinraal, who typically flies around the Eldin Mountains or Tabantha Frontier. Link needs to shoot the dragon with an arrow: he can shoot anywhere along the main body that isn't the horns, teeth, or claws (which will yield the other materials). Dinraal's Scale will fall somewhere on the land in the form of a light.

One of Dinraal's Scales is required to complete the Spring of Power Shrine Quest. Link must place the scale inside the spring. Doing so will open the way to a Shrine.
