Spiked Boko Bow
"An upgraded Boko bow bound with animal bone to boost its durability and firepower. Its craftsmanship is sloppy, but it's light and easy to use."
The Spiked Boko Bow is a common bow found in Breath of the Wild. It has a base power of 12, and is typically carried by Bokoblins. It is similar in appearance to the Boko Bow, however it is three times as powerful and a variety of bones have been affixed to the weapon. It is half as powerful as its much stronger Dragon Bone Boko Bow.
A Spiked Boko Bow can be found behind the waterfall in the River of the Dead, on the Great Plateau. Given its base power of 12, the Spiked Boko Bow is a powerful Bow while Link is still on the Great Plateau, but it quickly becomes outclassed by more powerful bows, as well as bows that have other features. While this is the only Bow found on the Great Plateau in the base game, many Bokoblins can be found wielding Spiked Boko Bow's on the Great Plateau in Master Mode. Throughout Hyrule, Spiked Boko Bow's are often used by Bokoblins and Lizalfos.
