EX Treasure: Phantasma

"EX Treasure: Phantasma" 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 Misko's EX Journal, which is rumored to be in the Outpost Ruins. In the Journal are clues to the locations of eight Treasure Chests, each containing a priceless relic stolen from Hyrule Castle by Misko. The Journal states the armor of fierce Phantoms can be found ruins of a battleground, ceremonial grounds and where soldiers gathered. It is possible to activate the second stage of the Quest by reading Misko's EX Journal without triggering any of the loading conditions for the Quest's activation. The Phantom Helmet can be found in a Treasure Chest buried in the northwest of the Colisuem Ruins. The Treasure Chest containing the Phantom Armor is buried in the southeast of the Sacred Ground Ruins. The Phantom Greaves are in a Treasure Chest buried near a wrecked Guardian Stalker in the southeast of the Hyrule Garrison Ruins. Each Chest can be dislodged from the ground using the Magnesis Rune, allowing Link to retrieve the Armor within. The Quest is completed once all three pieces of the Phantom Equipment have been obtained.
