There are two ways to increase your Stamina in Creatures of Ava, ensuring that you are always active in the creature saver game.

While Stamina Boosters temporarily boost stamina, Stamina Kits are one of three upgrades that permanently upgrade Vic's kit. Like Backpack Pockets and Health Kits, Stamina Kits are hidden in four biomes: Tamura Grasslands, Nari Jungle, Maruba Swamp, and Antar Dunes.

Several locations will ask you to complete quests and unlock parts of the map, with a few kit locations requiring you to return with new abilities in your kit. We found Stamina Kits in every biome in Creatures of Ava; however, once you leave a biome, you cannot return, with the Tamura Grasslands being the lone exception. This means you'll need to discover and collect all of the Permanent Upgrades in each biome before leaving.

Here you can find all the Stamina Kit locations on the Creatures of Ava map.
