Adui
Ascendant Reality Sever, upon reification becomes: "Grim" the Royal Reaper of Celestial Souls, whose power evolves to become an Aether Wave... A deluge of dimensional damage washing across the battlefield like Noah's biblical flood in an apocalyptic storm of lightning as thick as mountains and fireball explosions that come close to the first reified ability - just chained like a beaded necklace instead of rapid fire.
