E-Bomb

The E-Bomb is a magical bomb created using magical circuitry, magical rites, and materials mined from the world. It was created by the Dwarves near the end of The Great War as an ultimate attack upon the other races. It contained the power to kill an Old Deus. Because of Riku's plan, the original plan to test the E-Bomb on the Lucia continent (with intent to completely destroy it) was changed to testing it upon Avant Heim and the Ariena continent, then going to destroy all other races. While it overpowers the Áka Si Anse, it is only beaten in pure firepower by the Flugel's Heaven's Strike. It is stated by Riku from the data he obtained from the Werebeast alliance, that the E-Bomb can destroy entire continents, completely destroy the surrounding Elementals, and even kill an Old Deus.
