Should I Hand Over the Twinned Armor Set?

When It Makes Sense

• Good fit: You want the unique rewards tied to D’s twin brother and are comfortable with Fia being killed later in the questline. Handing over the armor reportedly advances his revenge plot and can let you recover the Twinned Set along with the Inseparable Sword after the Lichdragon Fortissax encounter in Deeproot Depths.
• Good fit: You have already completed Fia’s questline and obtained the Mending Rune of the Death Prince, or you do not intend to side with the Prince of Death ending. At that stage, the armor handover mainly changes an NPC fate and grants loot without blocking ending options.

When You Should Avoid It

• Warning sign: You want to keep Fia alive or prefer not to enable D’s brother’s revenge. If the narrative matters to you, giving him the armor leads to her death, which may conflict with a merciful or pro-Fia playthrough.
• Warning sign: You have not yet finished Fia’s questline or defeated Lichdragon Fortissax. Handing over the armor early can trigger unexpected NPC interactions, so consider securing any Fia rewards first.

Pros and Cons

Pros

• You can obtain the Inseparable Sword and recover the Twinned Armor Set, which is useful for collectors, achievement hunters, and faith-oriented builds.
• It resolves D’s brother’s revenge arc and gives a clear story payoff for players invested in D’s fate.

Cons

• Fia is killed as a consequence, removing her as a living NPC and potentially affecting roleplay or emotional investment.
• The choice is effectively irreversible for that playthrough; if you later regret it, you generally need a backup save or a new game to change the outcome.

Decision Checklist

• Have I completed Fia’s questline and obtained any items or runes I want from her before letting D’s brother act?
• Do I value the Inseparable Sword and the Twinned Set more than keeping Fia alive or avoiding revenge-driven outcomes?
• Am I playing a character where enabling D’s brother’s vengeance fits the narrative?

Alternatives to Consider

If you choose not to hand over the armor, D’s brother usually remains passive and Fia is not killed by him, though her questline may still conclude in other ways. You can keep the Twinned Set for your own fashion or build. If you are uncertain, make a backup save before speaking with him, or check an up-to-date Elden Ring wiki to verify current patch behavior. Waiting until the endgame is another safe option so the choice does not interfere with unfinished quest steps.

Final Recommendation

Hand over the Twinned Armor Set if you are a completionist, want the Inseparable Sword, and have already secured Fia’s quest rewards. Avoid it if you prefer to preserve Fia’s life, are still completing her storyline, or are roleplaying a character who would not fuel D’s brother’s revenge. Because NPC quest states can change with game updates and individual playthroughs can diverge, double-check the latest community guides or wikis before making a final decision.
