EX Treasure: Usurper King

"EX Treasure: Usurper King" is a Side Quest in. It is exclusive to The Champions' Ballad DLC Pack.

Overview
The Quest is obtained upon reaching Hyrule Kingdom and 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 Misko's EX Journal 2, which is rumored to be in the Deya Village Ruins. In the Journal are clues to the locations of six Treasure Chests, each containing a priceless relic stolen from Hyrule Castle by Misko. The Journal states the helmet of the self-proclaimed King of Shadows can be found in the mire of a valley of dead trees, south of Dueling Peaks. It is possible to activate the second stage of the Quest by reading Misko's EX Journal 2 without triggering any of the loading conditions for the Quest's activation. The Treasure Chest can be found buried between two dead trees on a small island in Tobio's Hollow. Using the Magnesis Rune, Link can pull the Treasure Chest out of the ground and open it once it is free to obtain Zant's Helmet, completing the Quest.
