Tip: Where is the statue that trades stamina for health? (gosunoob.com)

 The statue can be found at the outskirts of Hateno Village, in the Necluda region. It’s near Firly Pond, the tiny lake by the house you can buy. Once you’re in the village, head to the north side of the pond. It’s next to the outcrop with the flag on it, west of the bridge. The statue is different from the ones you’ve already visited – it has horns.

When you talk to it, it will take one of your heart containers and start the Statue’s Bargain side quest. Talk to it again, and it will allow you to choose whether you want a stamina upgrade, or your heart container back. After that, the statue will exchange the two for you whenever you want, at a cost of 20 rupees per conversion. It will actually give you 120 when you relinquish your upgrade, but it will ask for 120 in order to give you a new one.

It’s a great way to respec Link before a tough boss fight, or a particularly tiring endeavor. For example, if you’ve already visited most of the shrines but spent the orbs on stamina, you can ask the statue to change it into hearts so you can get the Master Sword.
