Should I Give Fia The Cursemark Of Death?

When It Makes Sense

• Good fit: You want to unlock the Age of Duskborn ending and complete Fia’s questline, which requires giving her the Cursemark of Death before you reach the end of the main story and mend the Elden Ring.
• Good fit: You are interested in fighting Lichdragon Fortissax, accessing the Remembrance of the Lichdragon, and exploring the deeper lore surrounding Godwyn the Golden, Destined Death, and Those Who Live in Death.

When You Should Avoid It

• Warning sign: You are committed to a different ending path, such as Ranni’s Age of Stars or the Lord of Frenzied Flame ending, because giving Fia the mark diverts quest resources and role-play weight toward the Duskborn outcome.
• Warning sign: You are playing an under-leveled, low-vigor, or holy-vulnerable build, since the quest eventually forces a demanding optional boss fight that inflicts substantial holy and lightning damage.

Pros and Cons

Pros

• Progresses Fia’s questline to its conclusion, opening the Age of Duskborn ending option and giving you the Mending Rune of the Death-Prince to use on the Elden Ring.
• Unlocks the Lichdragon Fortissax encounter, a unique Remembrance boss with distinct rewards, plus additional dialogue and the chance to acquire Fia’s associated items and armor set.

Cons

• It commits you to completing several more quest steps; missing a step, advancing too far in the main story, or failing to interact with Fia at the right time can still block the ending.
• The resulting boss fight can be punishing and may require respeccing, leveling vigor, raising holy resistance, or upgrading weapons before it feels manageable.

Decision Checklist

• Do you want the Age of Duskborn ending, or are you satisfied with the default Elden Lord ending or another alternative?
• Have you prepared adequately for the Lichdragon Fortissax fight, including leveling vigor, upgrading your primary weapon, and considering holy-resistant gear or incantations?
• Have you confirmed that you have not already advanced the main story or other NPC questlines to a point where Fia’s questline could fail or become unavailable?

Alternatives to Consider

If you do not want the Duskborn ending, you can skip giving Fia the Cursemark and pursue other endings such as the default Elden Lord ending, Ranni’s Age of Stars, the Frenzied Flame ending, or the Order endings tied to Goldmask and Brother Corhyn. You can also reach the end of the questline, defeat Lichdragon Fortissax, and still choose not to mend the Elden Ring with Fia’s rune, preserving the option to select a different ending at the final decision point. New Game Plus offers another chance to experience the questline if you skip it now.

Final Recommendation

Giving Fia the Cursemark of Death is the best choice for players who want the Age of Duskborn ending or who wish to experience Fia’s complete story and the Lichdragon Fortissax boss encounter. If you prefer a different ending, are role-playing a character opposed to Fia’s philosophy, or are not prepared for the boss fight, you should delay or skip this step. Because Elden Ring quest triggers and patch behavior can be subtle, check a current community wiki or guide if you are unsure whether your playthrough state still supports the questline.
