"A helmet much like the one Midna wore when she fought alongside the Hero of Twilight. If sold, this rare find can’t be replaced."
Midna's Helmet is a piece of armor found in Breath of the Wild. It was released as a part of the first DLC expansion for the game: 'The Master Trials'. It works similarly to the Diamond Circlet and the Guardian set of armor, since it provides Link with an increased resistance to attacks from the deadly Guardians.
