Spiked Boko Bat
"After much consideration by Bokoblins on how to improve the Boko bat, they simply attached sharp spikes to it. A skilled fighter can cause immense damage with this."
The Spiked Boko Bat is a two-handed wooden bat found in Breath of the Wild. It has a base power of 18, and is typically wielded by Red and Blue Bokoblins in the Necluda region. The weapon appears to be a modified version of the Boko Bat, but with additional spikes added to increase the damage output. It is wooden in design, meaning it will set fire if it is brought close to a flame.
Spiked Boko Bats are most commonly found being used by Blue Bokoblin and Black Bokoblin. With a power of 18, they are three times as strong as their standard Boko Bat counterpart, but they have the same, relatively low durability.
