EX Strange Mask Rumors

"EX Strange Mask Rumors" is a Side Quest in.

Overview
The Quest is obtained after purchasing The Master Trials DLC pack and upon reaching Hyrule Kingdom. The Quest will activate upon loading the overworld of Hyrule, which can be done by Traveling, reloading a save file, dying, or leaving an Ancient Shrine. When the Quest is activated, Link will be tasked with finding a copy of Super Rumor Mill EX, which is apparently in the Woodland Stable. In the book, Traysi discusses the Korok Mask and reports on a rumor that it is inhabited by a spirit that causes it to shake when it is worn and if friends are hidden nearby. The Mask is rumored to be in a Treasure Chest hidden a tree hollow in forest that causes people to become lost. It is possible to activate the second stage of the Quest by reading Super Rumor Mill EX: Volume 1 without triggering any of the loading conditions for the Quest's activation. The Treasure Chest can be found in the Lost Woods inside the hollow of a tree south of a pair of Torches with a Torch Weapon leaning against them. Retrieving the Korok Mask from the Chest will complete the Quest.
