With one swift movement, Ardante slashed his knife across Kaler's neck, beheading him. Or, at least, that's what would have happened.
Ardante felt something stopping the knife, he could not move his hand further. He felt that his weapon was stuck on something... "What is this..." He muttered.
In front of him, his knife met its target, however, Kaler still had his head attached to his shoulders. Ardante's eyes widened behind his helmet. "Impossible!" The knife was stuck in Kaler's flesh, only making a small graze.
"I will admit. You are the first person to even graze my diamond skin." Kaler commented, smiling behind his mask. "But it's time to end this." Kaler focused the energy in his body, or at least, what's left of it, and expelled it outwards in a large blast.
