As mentioned above, Tarnished spellcasters can find Ranni's Dark Moon inside of Chelona's Rise, a tower sealed with a magical barrier. To dispel this seal, the player must solve a puzzle identical to Liurnia's Tetsu's Rise and Limgrave's Oridys's Rise — "Seek three great wise beasts." Those who have completed the previous tower's riddles will recognize the "wise beasts" as three turtle spirits hidden in spots near the building. However, Chelona's Rise challenges the player to search the entire plateau for the ghosts, as only one sits within the tower's vicinity.
It is important to mention that Chelona's Rise is located within an area in Liurnia that only becomes accessible once Tarnished have made significant progress in Ranni's questline in Elden Ring. To reach the tower's plateau, adventurers must defeat 
Astel, Naturalborn of the Void, in the Grand Cloister and then ascend the lift at the Deep Well of the Ainsel River. From here, the player's next destination in the Witch's questline will be the Cathedral of Manus Sellus. However, if travelers head to the southwesternmost point of the zone, they will find Chelona's Rise, where Ranni's Dark Moon is stored.
