Ranni's quest is one of the longest in Elden Ring, but your time spent exploring the most secret locales across the Lands Between is worth it if you want to delve even deeper into Elden's Ring mysterious lore. You also need to complete Ranni's quest to unlock a secret Elden Ring ending, which has more substantial differences than in some other character quests.
Is it the best ending? Depends on how much you like witches—and giant swords.
