As the black wave of monsters continued their relentless charge forward, a powerful booming sound echoed in the field.
Several metal balls with glowing rune engravings flew across the sky, and when they landed on the black mass of flesh, they started exploding.
The first explosions tore open the tide like ripping flesh. Fire and frost bloomed at once. One metal sphere detonated in a blinding flash, the rune engravings burning white-hot as a concussive blast ripped through the front ranks. Bodies were flung skyward, limbs scattering across the snow like broken dolls.
Another sphere burst in a shriek of freezing mana. Ice spread outward in a violent bloom, flash-freezing monsters mid-stride. They shattered a heartbeat later, bodies breaking apart into jagged shards that clattered across the ground.
