Collecting treasure chests is a new pastime activity for players in Genshin Impact version 2.5. During the event 'Three Realms Gateway Offering,' a new area with the same geographical map as Enkanomiya will be available in the game.

On this new map, players must complete an Event Quest to collect rewards from the event. In addition, there are also new treasure chests spawned in various locations on the map. Since the map is temporary, Travelers are recommended to collect all chests, especially Luxurious Chests that give the most Primogem rewards before the end of version 2.5.

You can obtain the first Luxurious Chest in the Three Realms Gateway Offering north of The Narrows. The treasure chest is sealed behind Electro Monuments and Seelie. You must light up the monuments with Electro attacks based on the movement of the Electro Seelie.

The second Luxurious Chest can be claimed after completing a Time-Trial Challenge southwest of The Narrows. However, the challenge is locked behind three Seelies. You must find and follow those three to their garden to unlock the Time-Trial monument. A Luxurious Chest will spawn after you've completed the challenge.

The third Luxurious Chest is hidden behind another Time-Trial Challenge northwest of Evernight Temple. Similar to the previous treasure chest, you must find and send three Seelies back to their courts before the barriers surrounding the monument disappear. Complete the Time-Trial Challenge, and you will receive a Luxurious Chest.

You can find the fourth Luxurious Chest along with two other Precious Chests inside a locked gate with a sleeping Ruin Grader. However, you must activate the mechanism that was sealed behind four Electro monuments before the gate protecting the treasure
