Stamina in Genshin Impact is increased by collecting Anemoculus and donating it to Statues of the Seven.
Anemoculus is your ticket to a bigger endurance bar at Genshin Impact, and the more stamina you have, the more you can climb, run, swim and slide. These floating blue orbs are scattered all over the map in Genshin Impact, but they are thankfully marked on your minimap whenever you get close to them. The anemocule will appear as a star icon on your minimap, and it will usually float above you. Some will require you to complete a challenge or two to get there, but the majority simply require a gliding ace to grab.
Once you have an anemoculus on hand, visit one of Genshin Impact's many statues of the Seven scattered around the world. They are labeled on the map with a pointed blue orb, and you can visit any of them to donate. Once you are on a statue, interact with it and choose to “worship” it.
From there you will open the donations menu, which will tell you how many Anemoculus are needed to increase your stamina. You'll also earn other rewards, which is a nice bonus. You can bank whatever you have on hand, so don't be afraid to check in with the statues if you're near (they can be used to heal your party in a pinch).
Each increase in stamina will require more Anemoculus than the last, so step out into the world and start exploring. Eventually, you'll be able to climb, run, swim, and hover longer than before, which is a huge plus. Why are you still reading this? Go out and find the anemocule!
