The Headmaster concentrated, as the Impenetrables closed in. Focus all energy... he thought, and then:
BOOM!
"LIGHTNING WAVE!" the headmaster yelled, and as he swung his halberd, a huge blast of energy came out of it, slamming into his opponents.
They could not avoid it. Each was shocked into death, holes from the attack have a match on the other side of their body.
The Headmaster, weary from his expense of energy, sat down, trying to get his breathing coherent.
That's when he noticed that one was still moving.
It dragged itself into range, and then muttered something inaudible.
---------------------------------------------------------------------------------
BOOM!
Drael and the rest of the people fighting looked up to see the spectacular explosion. Drael's eyes widened as a figure shot from the explosion.
The peasants, seeing the explosion on the ridge where their masters stood, screamed and ran.
The last Impenetrable, a man with a spear, charged Assren.
Assren didn't notice until a spear struck through him. He screamed, and as the spear withdrew, toppled to his knees, and then fell face first into the bloody field.
Drael jumped at the Impenetrable, his swings considerably slower than his opponent's stabs.
He cursed as he lifted the heavy sword to block a spear.
He rolled to the side and then, finally, stabbed his blade through the spearman, killing him instantly.
