The Elden Ring Fia quest is one of the most significant in the game and that's because, as with Ranni, Dungeater, and Goldmask, it's tied to a potential ending (opens in new tab) that you can get. But Fia is a lot more unassuming than most of the other characters; it's not even clear how you start your quest when you first meet her.
After you get transported to the Roundtable Hold by Melina for the first time, you'll likely run into Fia's room while looking for stuff to steal. This perfectly welll meaning stranger will offer to give you a hug, and if you do, she'll tell you different stuff throughout the main game. She also plays a bit of a role in Rogier (opens in new tab)'s quest, if you happen to bump into him in Stormveil Castle.
In this Elden Ring Fia quest guide, I'll run through all of the main steps required to complete her quest and get her specific ending to the game. This will contain some endgame spoilers, so if you've somehow managed to avoid them so far and want to play blind, you should probably leave.
Elden Ring Fia quest summary
Here are the broad steps that you need to complete Fia's quest:
1. Meet Fia in the Roundtable Hold and receive her blessing.
2. Once you get to the Altus Plateau, speak to Fia to get the Weathered Dagger.
3. Give the dagger to D, Hunter of the Dead in the Roundtable Hold.
4. Return to find D murdered by Fia in the room just past Smith Master Hewg.
5. Complete the Ranni quest (opens in new tab) to the point where she gives you the Carian Inverted Statue.
6. Use the statue in the Carian Study Hall (opens in new tab) and make your way through to get the Cursemark of Death.
7. Head to the Deeproot Depths through the coffin in the Siofra Aqueduct or the Cathedral of Forsaken shortcut below Leyndell. Climb the roots in the Nameless Eternal City and fight the Fia's Champion boss.
8. Give her the Cursemark of Death then enter the Deathbed Dream to defeat Lichdragon Fortissax.
9. Claim the Mending Rune of the Death Prince and her outfit from her body.
10. If you gave D's armor set to his twin in the Siofra Aqueduct, he'll kill her, but you can receive his sword and get D's armor set back if you reload and return.
Should you let Fia hold you?
Elden Ring Fia hold you: Should you let her?
You first encounter Fia in Roundtable Hold, which is essentially the Firelink Shrine of Elden Ring. From the main room with the Table of Lost Grace, head through the doorway to the right of Diallos, then proceed through the door opposite. Fia is sitting on a bed close to a large open fire.
When you first approach Fia and talk to her, she'll ask to "hold you". It's a bit of an odd request, all things considered, so you're probably wondering what the catch is.
If you agree to let Fia hold you, you'll receive the Baldachin's Blessing item, a consumable that temporarily boosts Poise. The trade-off is that Fia gives you a minor HP debuff until you use the item. You can return to her for more Baldachin's Blessings whenever you need. Refusing her offer means you won't get the item or start her quest.
Elden Ring Fia quest: What to do with the Weathered Dagger
Now you'll want to head to Summonwater Village to meet D and defeat the Tibia Mariner boss. It's worth noting that this boss drops the Elden Ring Deathroot (opens in new tab) item, which is unrelated to this quest, but valuable all the same in unlocking bestial incantations. You should now be able to find D near the main table of the hold, though you can ignore him for now.
Once you arrive at the Altus Plateau using the Dectus Medallion (opens in new tab) or the Ruin-Strewn Precipice, go and talk to Fia. She'll hand you the Weathered Dagger, and ask you to find its owner.
Now head back to D in the main room and hand over the dagger. When you return to the Roundtable Hold, you will find that D has been murdered by Fia in the room at the end of the corridor by Smith Master Hewg.
Cursemark of Death location
Where to find the Cursemark of Death
Once you have the statue, head to the Carian Study Hall and place it on the altar. You'll now be able to make your way through, but you'll still have to fight Proprietor Miriam. The best tactic is to use a spell or bow that might knock her off the bridge. On the approach to the Divine Tower, you also have to face a Godskin Noble who suddenly appears.
Head up to the top of the Divine Tower and loot the Cursemark of Death from the corpse you find.
Twinned armor choice
Siofra Aqueduct Twinned armor choice
The next step of Fia's quest involves heading to the Deeproot Depths through the Siofra Aqueduct near Nokron. You will have unlocked this area after beating Radahn as part of Ranni's quest, since it's separate from the regular Elden Ring Siofra River (opens in new tab) region.
After the Mimic Tear boss, you'll arrive in a wooded area. Head north-east through the woods and past the jellyfish and you'll find a place to drop down into the Siofra Aqueduct. Make your way through, but be wary of the patrolling Crucible Knights. Just before the door to the Valiant Gargoyle boss, you'll find D's brother slouched on the floor.
If you choose to hand over the Twinned armor set, D's brother will kill Fia. This doesn't happen until much later, so it doesn't appear to affect whether you get her ending or not. You'll get the armor back eventually, too, as well as a new Elden Ring weapon (opens in new tab). If you don't hand over the armor, nothing will change.
Defeat Fia's Champions
Defeat Fia's Champions in Deeproot Depths
Now, defeat the Valiant Gargoyle boss. Draw the first over to the left side of the arena, and beat it as fast as possible, while watching out for its poison spewing move. Avoid the second while it's using the twinblade until it switches to axe, since the attacks are much slower and easier to dodge. Once defeated, head to the waterfall and climb in the coffin.
Now you're in the Deeproot Depths. Simply keep heading along until you find the Nameless Eternal City, then head up the tree roots to get to the highest point where you'll find a site of grace. Head into the arena to fight the Fia's champions boss. It's relatively easy, since they are all just NPCs, but be wary of getting ganged up on in the last phase. Once done, head over to Fia by the portal.
Talk to her and ask her to hold you when prompted. Keep talking to her and hand over the Cursemark of Death. You should now be able to interact with her to enter the "Deathbed Dream". If this option isn't available, fast travel away from the area, then return via the Across the Roots Site of Grace.
There is an alternate route if you've made your way into Leyndell and the Subterranean-Shunning Grounds as part of the Dung Eater quest. After defeating Mohg in the Forsaken Cathedral, hit the altar, and descend to the Frenzied Flame location. Hit the walls on the right side to uncover a room with a chest, then hit the wall behind that to open a way to the Deeproot Depths.
Also a side note: if you haven't beaten the Draconic Tree Sentinel to enter Leyndell, you can actually skip it by going through the portal located next to Fia. This portal will only unlock once you've beaten two shardbearers, however.
Getting Mending Rune of the Death-Prince
How to get the Mending Rune of the Death-Prince
Once you enter the Deathbed Dream, you'll need to face the dragon boss, Lichdragon Fortissax. Once he's been defeated, you're transported back out of the dream. Fia appears to be asleep, but you can loot her for the Mending Rune of the Death-Prince. This is the key item needed to get Fia's Ending and is used after you've beaten the final boss. You can also now claim Fia's outfit at her bed in the Roundtable Hold.
If you handed over the Twinned armor
If you handed the Twinned armor to D's brother
Once you've obtained the Mending Rune of the Death-Prince from Fia, you are free to leave the area. But if you chose to hand over the Twinned armor to D's brother earlier on, he'll show up when you next return and will be standing over Fia's body, having killed her.
Rest at the site of grace and he'll disappear, leaving you to claim the Twinned armor and the Inseparable Greatsword he left behind.
