Locrias' Blade spell generated an energy disc that moved as fast as a bullet and grew in size as it advanced. Unbreakable Anvil had limited destructive power, but incredible durability.
It had been devised to catch all the enemies it met in its trajectory and herd them right in front of Menadion's Unstoppable Hammer.
The Anvil advanced too fast, and its walls were too hard for the Upyrs to escape before the two Blade Spells met. The two energy waves collided, one folding into the other, without a single iota of energy being wasted.
"Come on, boys!" Trion yelled. "What's a forge without a fire? Let's smelt Meln's bastard sons with a Thousand Flames!"
The Demons of the Darkness breathed in unison, releasing a torrent of Origin Flames that burned at the captured enemies without affecting the Blade Spells. Caught between a hammer, a hard place, and a searing wave of flames, even the plant folk using their allies' corpses to fuel their regenerative abilities were destroyed.
