Genshin Impact's Lantern Rite has changed Liyue Harbor's appearance with the decorations and new interactable celebration materials. While roaming around the harbor, players must have come across a stall with 3 Luxurious Chests in front of it with no interactable options.
Although they look like dummies at first, they are now obtainable during the third stage of Lantern Rite Tales.
Genshin Impact: How to open the 3 luxurious chests at Liyue Harbor by completing the illumiscreen 3 quest
To unlock the illumiscreen-3 quest in Genshin Impact, players must complete all requests from Lantern Rite Tales-1 and Lantern Rite Tales-2.
Upon activating the illumiscreen request, players can visit Brother Qian at the harbor and solve the illumiscreen puzzle. The puzzle requires players to successfully arrange three screens to form a picture of the Divine Crane.
After solving the puzzle, Brother Qian will ask the players to collect three different treasures by visiting three different locations marked on the map. The location of the treasures in Genshin Impact is shown below.
The first two treasures will be guarded by many hilichurls, a mitachurl, and a puzzle to light four pyro torches that are pretty easy to deal with.
However, the third treasure, located at the Guyun Stone Forest, will be guarded by three Geovishap Hatchlings, who have immense resistance to physical attacks and good dodging abilities.
After defeating the hatchlings, players can find the last treasure and return to the illumiscreen stall at Liyue Harbor.
At this stage, Brother Qian will offer the players a reward for completing his request by unlocking the 3 Luxurious Chests. Players will get an interactable option to unlock the chests, and the illumiscreen 3 quest in Genshin Impact will be completed.
