Although the Darkdrift Knight expedition is just one of the standard Nightlords on the way to the secret final boss, Fulghor may as well be the top dog in Elden Ring Nightreign. He's incredibly tough to slay, so much so that I'd beaten every other Nightlord (yes, including Night Aspect) before returning to him—and I doubt I'm alone in this. Working out how to beat Fulghor, Champion of Nightglow, is potentially the toughest hurdle to overcome.
If you're trying to complete all the Elden Ring Nightreign Remembrances for each character, then I'm sorry to say that you'll be required to beat Fulghor on at least one occasion. Ironeye, the best character in our Nightreign tier list, demands you kill Fulghor in Chapter 6, and right after you unlock Revenant, you'll be sent to kill Fulghor or Gladius again, the first of the Nightreign bosses. It shouldn't be a surprise when I recommend you kill Gladius again over challenging the Champion of Nightglow.
