Fir wands are stated to align to wizards who are particularly suited to Transfiguration, and who have a tendency to survive "mortal peril". McGonagall was Transfiguration Professor at Hogwarts School of Witchcraft and Wizardry, and, in 1996, survived four simultaneous Stunning Spells taken to the chest with only a brief stint in St Mungo's Hospital for Magical Maladies and Injuries despite her age at the time. She also survived the whole of the Second Wizarding War, including the Battle of Hogwarts, despite being a prime target due to her close association with Albus Dumbledore.
