Elden Ring: How to complete Fia’s questline

Fia is a fascinating individual who you meet for the first time in Roundtable Hold. She has her own room behind the blacksmith's shop, and if you speak with her, she will ask if you want to be imprisoned there. This will grant you a blessing that will benefit you in combat. Despite her outward look, this NPC has a lengthy questline that will lead you to the furthest corners of the Lands Between. This is how Fia's questline in Elden Ring is completed.

Prepare yourself.

Get both D and Rogier to Roundtable Hold to begin Fia's questline. After you defeat Godrick, they will all arrive in the region. D can also be discovered outside of Summonwater Village in the northern portion of Limgrave. You must also speak with Fia several times and be embraced before you may begin Fia's questline. You must also beat at least one Sharbearer, such as Godrick, and ride Liurnia's Grand Lift of Dectus. Fia's questline can begin once all of this is completed.

Kill D

Return to Roundtable Hold and speak with Fia after obtaining a Great Rune and riding the Grand Lift of Dectus. She will hand you a Weathered Dagger after some brief chat. If you hand up the dagger to D, he'll tell you who it belongs to. Reload the region and enter the room past the blacksmith's location. Before you enter, you will hear a dialogue. When you enter the room, Fia will be standing over D's body.

Head to Deeproot Depths

Fia will advise you to proceed to the top of Deeproot Depths after D is dead. To do so, travel to Nokron and search for the aqueduct dungeon. Outside of the boss area, you can chat with D's brother and give him D's armor. This will allow you to access a unique section of Fia's quest. Defeat the dungeon's pair of valiant gargoyles. A coffin can be found at the base of the waterfall. Rest in the coffin before being taken to the depths of Deeproot.

Defeat more bosses

Go across the roots and into the ruins on the other side of Deeproot Depths after you've arrived. To get to the region upon the cliffs past the broken gargoyles, use the tree roots in the ruins. Go to the other side of the big boss arena. There will be a boss encounter in which you must kill five NPC foes. Reload the scene after the fight and speak with Fia, who is now sitting on a bench near to where the boss battle took place.

Obtain the Cursemark and defeat the dragon

Fia will inform you that she wants you to get the Cursemark of Death when you talk to her in the boss room. Part of Ranni's questline must be completed to earn this. It may be found at the top of Liurnia's Divine Tower. Reload the location after giving Fia the Cursemark. Fia is presently sound sleeping. Interact with her to confront Lichdragon Fortissax in a variant variation of the boss arena. After the battle, speak with Fia, and she will offer you the Death Prince's Mending-Rune.

Optional ending

While the image is the end of Fia's questline, you can go a step farther. Reload the scene after giving D's brother the Twinned Armor, and D's brother will be standing over Fia's body. Fia's armor set is now available for purchase. D's brother will be pleased if you speak with him. Kill him to reclaim the Inseparable Sword and the Twinned armor.
