Elden Ring: Fia Full Quest Walkthrough

Completing Fia’s questline will unlock one of several alternative endings in From Software’s Elden Ring.

Updated on July 31, 2024, by Nahda Nabiilah: Dragons are a bit of a rarity in Elden Ring. Players will encounter many dragons in their journey, but most of them are in the form of bosses, meaning they won’t respawn, unlike other enemies. While the Shadow of the Erdtree does increase the number of existing dragons, It’s still considered a small number. So, it’s essential to defeat each one of them to not miss out on any rewards. The Lichdragon Fortissax, for example, is a hidden boss that’s locked behind an NPC quest. Defeating it rewards a Remembrance as well as a decent number of Runes.

Inside, tarnished will fight against the Lichdragon Fortissax. Upon beating the dragon, players will gain the Mending Rune of the Death-Prince to unlock the Age of Duskborn Ending.

Additionally, beating the dragon grants 90,000 Runes and the Remembrance of Lichdragon. This item can be used at the Roundtable Hold to buy two Incarnations: Fortissax’s Lightning Spear and Death Lightning.

Fia, the Deathbed Companion is one of the many NPCs encountered at the Roundtable Hold once the first Shardbearer is defeated. She can be found in a bedroom next to where Smithing Master Hewg is located. At first, Fia will only offer Baldachin’s Blessing when Tarnished allows her to hold them.

However, upon unlocking Altus Plateau or defeating General Radahn in Elden Ring, Fia’s quest will be triggered, an essential factor for Lichdragon Fortissax’s location. Head to the Deathbed Companion and hold her to talk in secret to receive the Weathered Dagger . After that, Tarnished must give it to D, Hunter of the Dead which completes the first step of Fia’s questline in Elden Ring.

Elden Ring: How to Get to Radahn

Here’s where to find and how to reach Starscourge Radahn in Elden Ring, one of the main bosses.

How To Get The Cursemark Of Death In Elden Ring

The Cursemark of Death is a key item given to Fia to advance in her quest and fight the Lichdragon Fortissax. Acquiring said item is no easy feat as players must progress through a good chunk of Ranni the Witch’s quest to get it.

Firstly, exploring Caria Manor in Liurnia of the Lakes and defeating Royal Knight Loretta is a must. That’s because Ranni is inside Ranni’s Rise which is only accessible from Loretta’s boss area.

Next, Tarnished must travel all the way to Caelid and trigger the Radahn Festival. Defeating General Radahn will unlock Nokron, the Eternal City, making it possible to retrieve the Fingerslayer Blade. Give The Nokron Treasure to Ranni to receive the Carian Inverted Statue which can be used inside the Carian Study Hall to flip it upside down. Finally, head all the way to the top floor of the Divine Tower of Liurnia to obtain the Cursemark of Death.

The last step is to offer the Cursemark to Fia at the Deeproot Depths after defeating the Fia’s Champions boss, allowing the Deathbed Companion to lay with Godwyn and for players to enter her dream to fight the Lichdragon Fortissax secret boss in Elden Ring.
