Removes power

But just before they reached the exit, Darkstalker paused and regarded Turtle pensively for a moment. “I wouldn’t normally do this,” he said. “I always think an animus could be useful in some way, if handled correctly. But you managed to trick me once, and that makes me a bit nervous about you, so, I’m sorry.”
Darkstalker cupped his talons around Turtle’s face. “Enchant this dragon to lose all his animus power right now,” he said, “so that he shall never be able to cast a spell again.”
Turtle caught his breath, and caught it again, gasping with disbelief. A strange sensation scraped over his scales, like a powerful scrubbing brush scouring him clean.
It was gone. The faint tingling in his claws that had been there from the second he hatched. He’d never even known what it was — never guessed that it was a sign of animus magic. And now it had vanished forever.
