Dragonbone Boko Spear
"This Boko spear has been strengthened with fossilized bones. The bones are positioned outward so the fangs bite at the opponent. Beware Bokoblins carrying this weapon."
The Dragonbone Boko Spear is a two-handed wooden spear found in Breath of the Wild. Despite it having a low base damage, due to the nature of spears, it has a relatively high damage-per-second, which can take out enemies swiftly. The design, however, is simply a stick with some bones affixed to the tip, which signifies a fault in the durability sector.
The spear can often times be seen in the hands of Black Bokoblins all over Hyrule, but more prominently in the Akkala region. It is also occasionally found being used by Black Moblin and Blue Lizalfos.
