The Dark Moon Greatsword is the final reward in Lunar Princess Ranni’s questline. After defeating Astel and reaching the Moonlight Altar, enter the Cathedral of Manus Celes and give Ranni the Dark Moon Ring; the sword appears after the scene. It requires 16 Strength, 11 Dexterity and 38 Intelligence, and its Moonlight Greatsword skill adds frost and ranged projectiles to heavy attacks.
How to get the Dark Moon Greatsword
You receive the weapon at the end of Ranni’s questline, not as an early-game pickup. The final location is the Cathedral of Manus Celes, where Ranni is waiting beneath the cathedral after you reach the Moonlight Altar.

What Moonlight Greatsword does
Moonlight Greatsword is the weapon’s unique skill. Activating it buffs the sword; while the buff is active, regular and charged heavy attacks send out ranged projectiles. The cited reference lists the skill’s FP cost as 32. The skill is also described as adding frost to the weapon, complementing its listed frostbite buildup.

- Collaborating with George R.R. Martin to create the ELDEN RING mythos has been a genuinely delightful experience and a source of wonderful inspiration. The team is working hard to ensure that the world of ELDEN RING will be a fascinating place for players to explore, filled with peril and wonder from its furthest reaches to its lowest depths. This is a FromSoftware title through and through, rich in fantasy and RPG action. We sincerely hope you look forward to it.
- Building the world of ELDEN RING with Miyazaki-san and his team was a treat! The graphics, mythos, and action-RPG gameplay will deliver an unforgettable experience. I can’t wait for people to see what ELDEN RING has in store for them.” Said George R.R. Martin.
Is it a good fit for your character?
The key check is whether your build can meet the 38 Intelligence requirement alongside 16 Strength and 11 Dexterity. Its listed attack is split between physical and magic, and its skill suits players who want heavy attacks to reach targets at range. Those traits describe how it may fit a character; they do not establish a universal damage ranking or make it the best choice for every build.
What the weapon is
The Dark Moon Greatsword is a greatsword and one of Elden Ring’s legendary armaments. Its in-game description, transcribed by Eldenpedia, reads: “A Moon Greatsword bestowed by a Carian queen upon her spouse to honor long-standing tradition.”
