The All-Blade is a mystical weapon used by the All-Caste.
History
Mystical blades designed to kill magic-based threats, such as the Untitled[1] or Amazons, but cannot harm anything else.[2]
They can only be summoned in the presence of absolute evil.[3] The blades are powered by the soul of the wielder,[2] and can be powered by spilling the wielder's own blood.[4]
Jason believed that the blades were indestructible until Essence broke them.[3]
When Jason truly mastered the All-Caste's teachings, he gained access to the real All-Blades, becoming capable of summoning them to his hands at will.[5]
