Black Myth: Wukong‘s Luojia Fragrant Vines are one of the most important (and most rarified) items you can find, and they’re scattered over multiple locations.
These plants let you upgrade your Gourd, which can be the difference between winning a fight or returning to the closest Keeper’s Shrine. With enough Luojia Fragrant Vines, you can also upgrade your Gourd to a maximum of nine uses. Once it’s fully upgraded, you can acquire the secret Mythical-rarity Supreme Gourd by speaking to a certain NPC in Chapter Five. This bumps your uses to 10 and grants you an achievement.
