Jason explosion

He swept his spear sideways, met Jason’s javelin—and with a snap like a shotgun blast, the golden weapon shattered.
The explosion was hotter than the giant’s breath, blinding Jason with golden light. The force knocked him off his feet and squeezed the breath out of him.
When he regained his focus, he was sitting at the rim of a crater. Enceladus stood at the other side, staggering and confused. The javelin’s destruction had released so much energy, it had blasted a perfect coneshaped pit thirty feet deep, fusing the dirt and rock into a slick glassy substance. Jason wasn’t sure how he’d survived, but his clothes were steaming. He was out of energy. He had no weapon. And Enceladus was still very much alive.
Jason tried to get up, but his legs were like lead. Enceladus blinked at the destruction, then laughed. “Impressive! Unfortunately, that was your last trick, demigod.”
Enceladus leaped the crater in a single bound, planting his feet on either side of Jason. The giant raised his spear, its tip hovering six feet over Jason’s chest.
“And now,” Enceladus said, “my first sacrifice to Gaea!”
