Dark Souls 3: Ashes of Ariandel - How to defeat Sister Friede

There are two bosses in Dark Souls 3's Ashes of Ariandel DLC. The first is optional. To complete Ashes of Ariandel, you'll have to defeat the second, Sister Friede. Friede doesn't start out hostile. You'll find her in a cathedral approximately halfway through the Painted World of Ariandel, sitting near an altar.
