The Corrupted Bone Dagger is perhaps on of the most powerful of all daggers. Why, you may ask? Well my naive friend, it has the ability to corrupt who ever the tip penetrates, making this a highly coveted weapon among many evil factions. Its appearance is rare, and it is very expensive, like every other 'corrupted' weapon.
Like every other corrupted weapon, the Corrupted Bone Dagger is made by dipping a Bone Dagger in the Helmet of Garmadon.
