"The royal family of Hyrule collected historically significant outfits, but they were stolen by a bandit named Misko. One of the items stolen was a helmet of twilight... There's a journal that places the location of this treasure somewhere in the Outpost Ruins..."
— Adventure Log

EX Treasure: Twilight Relic is a side quest from The Legend of Zelda: Breath of the Wild. It is unlocked upon installation of the DLC Pack "The Master Trials". It requests Link to find the Misko's EX Journal at the Outpost Ruins. The quest guides Link toward the "twilight relic" treasure, a new Treasure Chest containing the Midna's Helmet, and located at the temple ruins soaked in the waters of Regencia River which refers to the Sage Temple Ruins. Link can find the chest in the northwestern building of the Sage Temple Ruins, and get it by using the Magnesis Rune.
