The protection from the Tyrant, supported by the Shared Chord Body and Bologue's own Ethereal Amount, converged three streams of Ether into a singular, pure force, all infused into the Bright Light Blade.
This Alchemy Armament acquired from Kedening, which Bologue later had appraised by Belli, was confirmed to be an ordinary Alchemy Armament that hadn't undergone a metamorphosis. Its strength largely related to its nature.
"Ether itself is a pure energy, and its Alchemy Matrix concentrates and releases this power. You can understand it as exchanging a large amount of Ether for maximized lethality."
Belli explained, introducing the Origin School that had similarities to it.
"The Origin School often uses such tactics. Once they master Ether to a certain degree, they can also shape Ether into Ethereal Blades and inflict damage."
