Viktor Krum used this curse on the Chinese Fireball dragon during the First Task of the Triwizard Tournament. However, because the dragon could not see, she crushed some of her eggs that she was protecting, which lost Krum points. Sirius Black, while talking to Harry through the Gryffindor Common Room fireplace, was going to suggest that Harry Potter use this curse on his dragon as well, but was interrupted by Ron Weasley coming down the stairs because he heard voices.

Olympe Maxime used this to force Golgomath's companions to drop Rubeus Hagrid when the giants became hostile towards them.
