Chaoseater is War's powerful sword, and the first weapon you acquire in the game. During the End-War.
Like its master, Chaoseater was stripped of its former strength
and power, followed by what may have been 100 years of imprisonment by the Charred Council. At the start of the game the sword is released from an underground fiery prison to be retrieved by War so that he may arm himself again.
Chaoseater has the semi-unique ability to absorb Chaos energy from defeated enemies, hence the name, and this energy is used to unleash Wars powerful Chaos Form. It could be assumed that the true form of Chaoseater is the form it assumes while War is unleashing his Chaos Form, taking on great size and power in the shape of a flame-engulfed sword.
Different effects to the facial engravings occur based on the swords current enhancement. Hellfire sets the blade on fire increasing damage and giving the possibility of catching the enemy on fire with attacks. Another example is the Carnage enhancement which makes the blade take on a bloody appearance while increasing the amount of chaos energy you gain.
A powerful sword that the Red Horseman will carry into many battles for judgement in the never ending war between the kingdoms of Heaven and Hell.
