Dinraal's Claw is an item from The Legend of Zelda: Breath of the Wild. It can be obtained by shooting Dinraal's claw during an airborne encounter. The dragon travels from the Eldin Great Skeleton in the Eldin Mountains through Tanagar Canyon.
Unlike Dinraal's Scale, Dinraal's Claw does not play a role in the story or any quests and is simply a rare material dropped by the Dragon which has a variety of uses.
Link can use Dinraal's Claws as a material to upgrade certain Armor via Great Fairy. Link can also sell it to shops and merchants for 180 Rupees or to Kilton at the Fang and Bone for 80 Mon. It can also be used in Cooking as an additional ingredient to increases the chances of critical success boosting the effects of certain cooked food dishes or Elixirs.
