- "Masks...You have...a lot. You, too...Will you be...a mask salesman?"
- — Lunar Child
There is a side quest Link can complete to obtain the Mask of Truth. Once the Happy Mask Shop in Hyrule Castle Town opens, Link can borrow a mask from the shop in order to sell it to someone else and return the money to the Happy Mask Salesman. Once Link manages to sell four of the masks, he is given the Mask of Truth. By this time, Link can also switch between the different masks.
The Mask of Truth can be used to listen to the various Gossip Stones scattered throughout Hyrule. They each tell Link random facts; some facts are more important than others. Additionally, it can be used (prior to traveling to the future for the first time) to obtain a Deku Nut carry limit upgrade on the Forest Stage.
Masks are an essential part of The Legend of Zelda: Majora's Mask. Other than the eponymous Majora's Mask, there are twenty-four collectible masks, four of which transform Link into an entirely different race. These masks are the Deku Mask, Goron Mask, Zora Mask, and the Fierce Deity's Mask. The other twenty masks serve lesser purposes, only used in brief portions of dungeons or for a side quest. Three of the four transformation masks, as well as the Gibdo Mask and Kamaro's Mask are made from purifying someone with the "Song of Healing", which in turn results in a mask. If Link gives the Lunar Children all of the non-transforming masks, he will receive the Fierce Deity's Mask from the fifth lunar child.
It has been thought that masks in The Legend of Zelda: Majora's Mask could be based off of things from the "real-world". An older coin of New Zealand has a mask that looks somewhat similar to Majora's Mask. Other masks in the game have also been thought to be based off of other things. The Kamaro Mask has been thought to be based off of the Trance Dancer mask, worn by Maori people. The Bremen Mask has been thought to be based off of another Maori mask called the Batik Flame Mask. Other masks and things in the game have also been thought to be based off of Maori masks and items.
The Hero's Charm allows Link to see an enemy's health. Unlike the other masks in the series, this one is equipped not as an item, but through the equipment sub-screen.
Also, in the Nintendo Gallery in Forest Haven, on the wall behind Carlov the Sculptor; there can be seen the Bunny Hood, the Goron Mask, the Keaton mask, and a fourth mask that looks very similar to the All-Night Mask.
Mayor Hagen collects masks and has many of them on the wall in his home. Identical masks can also be found on the Royal Hyrule Library's walls. The masks can be knocked over if Link uses the Pegasus Boots to ram into the wall, and occasionally drop Rupees. A book called A History of Masks can be found by Link in Mayor Hagen's Lakeside Cabin and must be brought to the Royal Hyrule Library in order to progress in the game.
The Hawkeye, which Link can purchase after Malo opens Malo Mart, increases visual acuity and can be used in conjunction with the Hero's Bow to create a "sniper scope." Because Link goes into the first person view when wearing the Hawkeye, he is never actually seen wearing the Hawkeye by the player.
After Wolf Link obtains the Ordon Sword and Ordon Shield for Midna, upon entering the Twilight Realm, Midna can be seen wearing the Ordon Shield on her face as a Mask, before she puts it away for safekeeping. Shadow Beasts wear similar shield-like Masks on their faces as well.
Several masks can be worn by Link as head armor, granting different stats or effects. Kilton the monster researcher who runs the Fang and Bone, stocks several masks based on monsters. These masks allow Link to disguise himself as different monsters, causing them to view Link as one of their own kind and not attack unless hit. Some masks are part of armor sets like the Radiant Mask and Stealth Mask, which grant certain bonuses when worn with the entire set.
Several featuring masks returns in the game in reference to previous episodes. Link can obtain two of them them by using the amiibo Rune with different amiibo. The Fierce Deity Mask is a special head armor from the "Fierce Deity" equipment along with the Armor, Boots and Sword obtained with the Link Majora's Mask amiibo of the Legend of Zelda: 30th anniversary series. The Sheik's Mask based on Sheik is obtained with Sheik amiibo and makes Link resemble him if worn with the Stealth Chest Guard and Tights. Three featuring masks can be obtained upon installation of the DLC pack The Master Trials and completing a few new side quests. The Korok Mask resembles the leaf mask worn by Makar and allows Link to detect hidden unnamed Koroks. Midna's Helmet is a reference to the piece of the Fused Shadow worn by Midna in her cursed imp form. The Majora's Mask causes Bokoblins, Moblins, Lizalfos and Lynels not to spot and attack Link.
Members of the Sheikah Yiga Clan wear mask featuring the upside-down Sheikah eye symbol used but Link cannot get it.
Some Masks appear in Hyrule Warriors as Badges that enhances characters. The Fierce Deity's Mask Badge gives characters more Special Attack gauges. The Hawkeye Badge increase the duration of bow and arrow power-ups.
Young Link carries two masks on his person, the Fierce Deity's Mask and the Keaton Mask. Young Link uses the Fierce Deity's Mask to transform into the Fierce Deity and when his Magic gauge is full, instead of playing the Ocarina of Time to convert SP in MP he will put on the Keaton Mask and pretend like he is going to transform with it but stops and laughs instead, though this only works if he is not in his Fierce Deity form.
