If you've made it as far as the Floating Cemetery in Clair Obscur: Expedition 33, there's no doubt you're familiar with the various White Nevron side quests found across the Continent. This particular White Chalier Nevron in Floating Cemetery is a bit different, however, and will challenge you to a duel when you confront it in the courtyard. At this point, your decision about whether to kill or spare the Chalier in Floating Cemetery should largely depend on your decisions with the previous White Nevrons you've run into.
