Annihilation

The rune produced a blinding light that engulfed everything within a hundred meters of the rune before shooting into the sky. 

"Oi, oi, oi!" Anna gasped while rushing away, barely avoiding it. Her instinct was telling her that she would survive this attack, but this wide-range attack's main purpose was annihilation. 

When the pillar of light disappeared, Anna dropped her jaw to the ground. 

"Is this for real…" Anna looked at the devastation that the rune brought. The ground cracked and a portion of it actually evaporated. The beasts looked like they were fried from the inside, their skin and flesh were melting. Out of seven hundred demons, only less than a hundred survived. 

Only those Advanced Level Demons or above had the chance to actually withstand such abilities. Even then, the Advanced Level Demons sustained heavy injuries and were even close to dying.
