After defeating Rennala, Queen of the Full Moon in Elden Ring's Academy of Raya Lucaria, players will encounter a chest. Fans will not be able to open Rennala's chest straightaway, though, as they must first obtain the Discarded Palace Key. This guide will detail exactly where players can find that key, allowing them to unlock the Raya Lucaria Grand Library chest in Elden Ring and claim the reward that is inside.

Opening Rennala’s treasure chest in Elden Ring
In order to get inside the chest, you need to progress Ranni’s questline to its absolute max. Ranni the Witch can be found at her tower, Ranni’s Rise, in northeast Liurnia. Once you’ve met and agreed to help her, you will need to complete several objectives.

The only way to open the chest near Rennala in Elden Ring is by following Ranni's storyline by entering into servitude to the Lunar Princess Demigod. Her main storyline begins once Tarnished has defeated Starscourge Radahn of Caelid, thereby gaining access to the underground Eternal City of Nokron. After speaking with Ranni and her subordinates within Ranni's Rise, the protagonist must retrieve the Fingerslayer Blade from Nokron, hidden within a building in the Night's Sacred Ground. Afterward, Ranni will leave the tower, never to return.

Upon speaking with Ranni, players will receive the Carian Inverted Statue, which they should place on the pedestal in the Carian Study Hall to the east of the Academy Gate Town in Liurnia. Elden Ring fans must then work their way through the inverted Study Hall, cross over to the Divine Tower of Liurnia, and collect the Cursemark of Death. With this item in hand, players should return to the area with Ranni's Rise, climb the ladder in Renna's Rise to the northeast, and use the portal at the top.

After defeating the Baleful Shadow, you will earn an item called the Discarded Palace Key. This key is the item you need to open Rennala’s treasure chest. Fast travel back to the Raya Lucaria Grand Library and open up the chest using the key. You will find a Dark Moon Ring inside, which is needed for an area in Nokstella after the Baleful Shadow’s room.

Elden Ring is available on PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and PC.
