Dragonbone Boko Shield
"This Boko shield is reinforced with fossilized bone. Its defensive capabilities are respectable, but its predictably slipshod craftsmanship spells low durability."
The Dragonbone Boko Shield is a shield found in Breath of the Wild. It has a base defense of 25, and is almost exclusively worn by Black Bokoblins in the outer regions of Hyrule, such as Tabantha and Ridgeland. Rarely, it can be seen wielded by Blue Lizalfos and Stalkoblin.
It is similar in design to previous renditions of the Boko Shield and Spiked Boko Shield, but it is strengthened with animal bones that are secured to the wood for extra defense. While its strength is a significant improvement over the weaker Boko Shield, it holds a durability of just 8, still making it one of the most fragile shields in the game. Only its weak Boko Shield counterparts and the Lizal Shield have lower durability.
