As I was in the air, I threw out the dagger with all my might.

Or course, it only managed to pierce through its feathers. Erosion wasn’t much sharper than any regular dagger, so it was impossible for it to pierce through the divine bird’s heart. Spikes of sand continued to appear.

“Release first stage restrictions: Battering Ram!”

The scythe changed into the shape of a battering ram. It was supposed to be a siege weapon used by multiple people to break open the walls of a fortress, comparable to a Servant with a level D Mana Burst skill. It was the most powerful weapon that Add could become. I let all of my remaining Magical Energy flow into it, and crushed all the incoming spikes of sand.

“Aaahhhhhhhh!”

I swung the battering ram downward forcefully, and into the golden dagger.

The divine bird (Hermes) faltered dramatically.
