With difficulty he dragged it over himself, murmured, 'Nox,' extinguishing his wand light, and continued on his hands and knees, as silently as possible, all his senses straining, expecting every second to be discovered, to hear a cold clear voice, see a flash of green light."
- — Harry uses this, invisible, whilst crawling through the tunnel into the Whomping Willow.[src]
