I guess my favourite so far would have to be the end of Chapter IX, which is the first team fight, and it starts with a truly misguided attempt by a character who lost her powers long ago trying to bluff that she still has them to somebody with the powers of a god:
“I warned you,” Stella snarled, holding out her hand and beginning to cast. “Powers of the universe, hear my prayer: grant me access to the laws of nature and all of its powers. Grant me the power of infinite destruction and the death of gods. Place the magic of all creation in my hands and bind it to my will–” The thief’s expression didn’t change, but the spike of masonry pivoted towards her. “–and I don’t think he’s buying it – run!”
She grabbed Adam and pulled him behind their rental car. The spike of masonry crashed through it, ripping open the cab, the tip stopping only an inch away from her nose. Then the car was ripped away from them and tossed aside by an unseen hand. The thief hovered before them, glaring. “That was very impolite,” he said, raising his hand. A massive spike of masonry ripped itself from a wall, the wall collapsing into a heap of rubble, exposing the building interior. It trained itself directly at her.
Stella grabbed Adam’s hand and squeezed. “I’m sorry, my wonderful love,” she said. “I think I just got us killed.”
The spike accelerated towards her. She closed her eyes.
And then her world exploded.
