The Legend of Zelda Breath of the Wild treats masks very differently from the rest of their items. Unlike weapons and shields, masks do not deteriorate or ever break. Each masks has its own effect to protect Link from different situations. Swap these items to take on different challenges.
Masks can either be purchased from Kilton, the Monster Merchant who owns Bone and Fang, or they can be obtained after using Amiibos and the Amiibo Rune on the Sheikah Stone. The first time Link encounters Kilton will be at the left eye of skull lake in the Akkala region (northeast part of the map). After the first meeting, he will appear either at skull lake or at each village and town around Hyrule, but he will only show up at night. See the Bone and Fang page for more info.
