Spiked Boko Shield
"A Boko shield made of slightly stronger wood and reinforced with animal bones."
The Spiked Boko Shield is a shield found in Breath of the Wild. It has a base defense of 10, and is first found wielded by Blue Bokoblins on the Great Plateau. The appearance is very similar to that of the Boko Shield, but bones have been affixed to offer additional defense.
With a defense power of 10, it is more than three times as powerful as the base Boko Shield. However, with a durability of just 7, only the base Boko Shield breaks more frequently. The shield is related to the much more powerful Dragonbone Boko Shield, which has a a strength of 25, but its durability score of 8 is barely bigger than the Spiked Boko Shield.
Outside of the Great Plateau, Spiked Boko Sheilds can be seen wielded by Blue Bokoblin on the pathway that leads through the Dueling Peaks. Occasionally, the Spiked Boko Shield can be found wielded by a Stalkoblin, Black Bokoblin, or a Lizalfos.
