The Whiteclad Noble is a boss in Black Myth: Wukong you encounter shortly after the Marsh of the White Mist Keeper’s Shrine in the Bamboo Grove. The boss fight against this snake-like warrior is divided into two phases: his “human” form and his “true” form.
At this early stage of the game, there’s not much scope in your build, and the Whiteclad Noble isn’t especially vulnerable to any particular kind of attack anyway. As with many bosses in Black Myth: Wukong, the key to beating him is understanding his attack patterns, and using effective counter-attacking patterns of your own.
