A gourd in Black Myth Wukong has many uses, but it’s primary use is to either buff the health of the player or to buff other status such as increase in attack for a certain amount of time. You start with the most basic Gourd in the first chapter – the Old Gourd, which can be upgraded to Medicine Gourd, Healing Gourd, Medicine Sage Gourd, Medicine Master Gourd, or Supreme Gourd. The best Gourd in Black Myth Wukong is the Supreme Gourd followed by the Immortal Blessing Gourd, and Xiang River Goddess Gourd. Here is how to get these Gourds in the game.
How to Get Supreme Gourd in Black Myth Wukong
If you wish to get the Supreme Gourd, the first thing you must do is upgrade the current gourd to 9 healing powers. You need the Luojia Fragment Vines and then go to the Black Wind Mountain > Bamboo Grove > Marsh of White Mist to upgrade the gourd with the Shen Monkey.
Once you have the Medicine Buddha Gourd, you must be in Chapter 5 and then go to Rakshasa Palace in Furnace Valley in Flaming Mountains. Spawn at the fast travel and go up the stairs, past the bridge. Follow the path on the left going past the giant red boss. Then, go over to the room indicated in the 2nd image below to find Old Man NPC.
Go over the dialogues with the NPC and then interact with the Camp Fire to unlock the Supreme Gourd.
