Albus Dumbledore's multiple stunner

This was a powerful spell, most likely invented by Dumbledore himself. It is a streak of silver light, with a sound like a gunshot, powerful to make the whole ground tremble, and stun more than one person. Albus Dumbledore used this in 1995 to make his escape when Dumbledore;s Army was exposed to the Minister. With it, he stunned John Dawlish, Dolores Umbridge, Percy Weasely, Cornelius Fudge, Kingsley Shacklebolt and Marietta Edgecombe. DO NOT REDIRECT TO DUMBLEDORES FORCEFULL SPELL.
