Stamina Vessels in Zelda: Tears of the Kingdom are permanent upgrades for Link's Stamina stat. Much like in Breath of the Wild, Stamina Vessels are acquired from Goddess Statues by turning in Lights of Blessing, which are key items obtained after completing each Shrine of Light. Stamina Vessels grant Link an increase to his Stamina Wheels, allowing him to perform more actions that utilize this resource before requiring a short break. Stamina Vessels share their acquisition method with Heart Containers and players are free to choose which upgrade they want for Link.
Zelda: Tears of the Kingdom Stamina Vessels Overview
How to Obtain Stamina Vessels in Zelda: Tears of the Kingdom?
Stamina Vessels are closely tied to the Goddess Statues found in each major settlement and other locations in Hyrule. The main function of Goddess Statues is to reward Link with either a Heart Container which increases his maximum number of Hearts and allowing him to take more damage before dying, or a Stamina Vessel, increasing his maximum Stamina and allowing him to perform more actions that utilize this resource. Each Heart Container grants one Heart and each Stamina Vessel grants a 1/5 segment of a Stamina Wheel.
Link can obtain these upgrades by turning in 4 Lights of Blessing at any Goddess Statue. A Light of Blessing is awarded for the completion of each Shrine of Light, of which there are a total of 152. Link is free to choose which upgrade he wants when interacting with a statue, except for the very first one encountered at the Temple of Time near the beginning of the game which forces him to pick a Heart Container.
The Horned Statue from Breath of the Wild returns, providing Link with a means to respec his main stats. This demonic-looking statue is locked behind a hidden passageway in the Emergency Shelter, an underground bunker beneath Lookout Landing. To gain access to it, you must first progress through the Main Quests up to Regional Phenomena, a multi-part quest assigned by Purah. Complete at least one leg of this quest, including one of the associated Temples, then return to the Emergency Shelter and speak to Jerrin to begin the Who Goes There? quest. The small crawlspace in front of her should have now opened, leading to a bunch of rocks blocking the path. Destroy the first set of rocks you find and then the ones on the right to find a cell where the Horned Statue is waiting.
The Horned Statue functions the same way as it did in Breath of the Wild. Link can surrender one of his essences, namely a Heart Container or Stamina Vessel to the statue. For each one he surrenders, he will receive 100 Rupees. Link can then continue surrendering essences or choose the "I want one back" option, which allows him to pick between a Heart Container or a Stamina Vessel, essentially allowing him to trade Hearts for Stamina and vice versa. Note that each time you request for an essence back, you must pay the statue 120 Rupees. This technically means each stat costs 20 Rupees to respec.
What is the maximum amount of Stamina in Tears of the Kingdom?
Link starts off with one full Stamina Wheel and can have a maximum of three full wheels. Since each Stamina Vessel grants 1/5 of a wheel, a total of 10 Vessels are needed to reach maximum Stamina.
There are a total of 152 Shrines of Light in Zelda: Tears of the Kingdom— 120 on the Surface and 32 in the Sky Islands. This equates to 38 total Goddess Statue Upgrades which can be divided freely between Heart Containers and Stamina Vessels.
Why are Stamina Vessels important in Zelda: Tears of the Kingdom?
Similar to Breath of the Wild, the vast majority of Link's actions will consume Stamina. This applies to both exploration and combat actions including sprinting, gliding, climbing, performing special attacks, aiming the bow in mid-air, and many more. Managing your Stamina is important as it can mean the difference between life and death in varying situations.
Additionally, Stamina ties heavily into the acquisition of the Master Sword in Tears of the Kingdom. Link's iconic weapon has found itself lodged in the forehead of the Light Dragon, a celestial being that roams the skies of Hyrule.
While Link can utlize a variety of ways to make it up to the Dragon even in the early game, pulling out the Master Sword employs a mini-game that will require at least 2 Full Stamina Wheels to accomplish. Consuming Food that grant temporary increases to Stamina will not work for this purpose.
