Xenoblade Chronicles has many quests for players to run, and one of them is the Giants Key Quest. It is a part of a quest chain that involves the Exile Fortress and Nopon merchants. All along the way, players will have to face off against some unique high-level monsters that will eventually lead to bagging some valuable rewards.
However, navigating through Satorl Marsh isn’t exactly easy for players, even after improvements from the Definitive Edition maps. After going through this guide, players will know where to find the Giants Key along with the schematics to successfully defeating the Deluded Ignas. So let’s begin!
Xenoblade Chronicles – How to Complete Giants Key Quest

Once players arrive at the location from the map above, towards the Western side of Satorl Marsh, they would have successfully rescued Kacha from the Exile Fortress, thereby triggering the Giants Key Quest. The next step involves locating the Deluded Ignas Kacha that protects the Giants Key.
Players need to make their way to the Silent Obelisk landmark and head over to the West side of the Exile Fortress. To find the Silent Obelisk landmark, players can instead go to Glowing Obelisk and proceed to follow the river – West. Stay on the river’s path until players reach the Northern edge of the Fortress and move South.
