I Finally Wielded the Dark Moon Greatsword (After a Dragon Called Me a Tarnished Flea)
Obtain Elden Ring's Dark Moon Greatsword through Ranni's quest to unleash freezing crescent arcs with its Moonlight Greatsword skill.

Let me tell you about my on-again, off-again relationship with a weapon that moonlights as both a fashion statement and a boss deleter. You'd think by 2026 I'd have every inch of the Lands Between memorized, but no—the Dark Moon Greatsword still had me running in circles like a headless chicken wearing a Burger King crown.
If you're still smacking demigods with a rusty longsword and wondering why your damage looks like a tickle fight, it's time to upgrade. Dark Moon Greatsword is one of those "shhh, just let the blue moonlight do the talking" weapons. It scales with Intelligence, Dexterity, and Strength—a classic case of a sword that went to college but still works out. The unique skill, Moonlight Greatsword, costs 40 FP and sends out a crescent arc of freezing death. It's got reach, it's got flair, and it makes you feel like the protagonist of your own tragic anime.
But getting it? Oh boy. You might as well enroll in Ranni's School of Interdimensional Errands because this weapon is locked behind a questline longer than the line for Radahn’s autograph at Caelid Comic-Con.
The Witch, the Ring, and the Attitude
First, you need to meet Ranni, the four-armed doll with a voice so calm you'd think she just came from a spa. She hangs out at Ranni's Rise, behind a spectral dragon that politely asks you to turn back. Once inside, you pledge your service. And then she sends you on a to-do list that would make a Finger Maiden weep.
You'll be chatting with Blaidd (a wolf-man who is somehow the emotional core of this quest), visiting the eternal city of Nokron, and eventually stealing the Fingerslayer Blade. Along the way you'll pick up the Miniature Ranni Doll, which you can talk to at a Site of Grace. Do it enough times and she breaks character—giving you the side-eye through her tiny porcelain face. It's weirdly adorable.
Eventually you'll gain access to the Lake of Rot. Yes, that lovely scarlet-tinged hellscape. You'll tiptoe through fungal nightmares and face Astel, Naturalborn of the Void—a giant cosmic bug that genuinely looks like it was designed after a late-night pizza order gone wrong. Beating Astel gives you access to the Moonlight Altar above Liurnia. And that's where the real fun begins.
A Dragon, a Ring, and a Very Deep Hole
Before you can claim the sword, you need the Dark Moon Ring. You get it from the chest inside the Grand Library of Raya Lucaria after progressing Ranni's quest far enough. It's a delicate little trinket that reads: "A symbol of a cold oath." Romantic, isn't it? Without this ring, the final step is just a sightseeing trip.
Now, head to the Moonlight Altar (accessible via a lift from Astel's boss arena in the Lake of Rot). The moment you step onto that glowing plateau, a chill runs down your spine—because soaring above you is Glintstone Dragon Adula. This isn't just any dragon; this is a spell-slinging, tail-swiping parking enforcement officer who has taken a personal vow to keep you away from Ranni. Adula teleports around like an ex who knows your schedule, and hitting her with melee sometimes feels like trying to slice fog. But once you put her down (or simply sprint past, because self-care is important), you can finally reach the Cathedral of Manus Celes.
Inside the ruined cathedral, ignore the altar and head to the giant hole in the floor. This is not an architectural defect—it's your VIP entrance. Drop down carefully (the fall damage will absolutely judge you if you're not at full health), and you'll find Ranni waiting next to the scaly remains of her Two Fingers—her old cosmic parole officer.
This is it. The moment of truth. Walk up to her, offer the Dark Moon Ring, and watch as she slides it onto her finger with the gravitas of a moon priestess. She then… vanishes. But in her place, you get the weapon you've been dreaming of: the Dark Moon Greatsword, glimmering with frosty promise.
Why This Sword Absolutely Slaps
| Attribute | Scaling at +10 |
|---|---|
| Strength | D |
| Dexterity | D |
| Intelligence | B |
It deals split physical and magic damage, and procs frostbite faster than you can say "Let me solo her." The charged heavy attack after activating Moonlight Greatsword sends a wave of frost that can stagger even late-game bosses. Pair it with the Godfrey Icon talisman and Ranni's signature hat for maximum style points.
No kidding, the first time I used the skill against a Tree Sentinel, the poor guy didn't even finish his wind-up. He just stood there, frozen, probably reconsidering his life choices. I may have whispered, "Yeah, you better stand down."
Tips from Someone Who Got Lost Six Times
-
Talk to the doll repeatedly at the Ainsel River Main Site of Grace until she gets annoyed. That's the secret trigger for the next stage.
-
Bring preserving boluses for the Lake of Rot, or just accept that you'll be inventing new swear words.
-
Adula is optional for the sword. If you're underleveled, ride Torrent faster than your anxiety.
-
Don't forget the ring. I repeat: don't forget the ring. I once made the whole trip, stood before Ranni, and realized the ring was still in my chest. The emptiness I felt was deeper than that cathedral hole.
By the time you finally hold the Dark Moon Greatsword, you'll have traversed underground cities, murdered a space bug, and possibly developed a phobia of scarlet water. But oh, is it worth it. This sword doesn't just look good—it carries the weight of a journey that feels personal. Every slice of moonlight now feels like a nod from Ranni herself, wherever she’s off to.
So gear up, Tarnished. The path is long, the dragon is smug, and that hole in the floor is deeper than it looks. But on the other side? A legendary weapon that will have people messaging you, "What sword is that?!" just before they get turned into a popsicle.
