- "[Collaboration: Xenoblade Chronicles 2]
Essential gear used by a boy who seeks sunken treasure in the Cloud Sea. It's a rather rare find."
- — In-game description
Upon an update (November 9th 2017) game update installation and after the side quest "Collaboration: Xenoblade Chronicles 2" is triggered, Link is guided to find and discover the "Salvager" treasures, three new Treasure Chests containing the "Rex's costume".
It is obtained from a special Treasure Chest which falls from the sky in the form of a red shooting star that appears when Link walks on the southern end of the Bridge of Hylia at night. The shooting star crash lands on the eastern shore of the lake near the bridge's south end where the southern pier is located. The chest emits a column of red light similar to a crashed Star Fragment and features a Star Fragment symbol on its lid. After crashing, the Treasure Chest will remain at the impact site (respawn there if it is moved with Magnesis) until its contents are removed.
