Remanent Reminiscence is a melee sword in Duet Night Abyss that leans into charged attack loops and sustained burst windows. Its defining perk lets you conserve Combo Points on charged attacks, making it a natural pick for builds that revolve around big, commit-heavy hits. You may also see the name written as “Remnant Reminiscence.”

How to get Remanent Reminiscence (blueprint and crafting)

Weapons in Duet Night Abyss are earned through the Secret Letter and Covert Commission systems. You’re looking for a weapon-category Covert Commission that can award the Remanent Reminiscence blueprint and its materials.

  • Progress the story until you can comfortably clear Covert Commissions (missions are set at level 40).
  • Enter a Weapon Covert Commission and spend the appropriate Secret Letter. Objectives rotate hourly, but the reward pool for the Letter stays consistent.
  • On a successful clear, you’ll be offered three items pulled from that Letter’s pool. Pick one. For weapons, you only need the blueprint to drop once to unlock forging.
  • Continue running the same Letter to farm the crafting materials for Remanent Reminiscence. Those materials drop from the same pool as the blueprint.
  • Craft the weapon once you have the blueprint and required materials.

Secret Letters are acquired by exchanging Secret Letter Clues, and you’ll keep a steady flow by completing dailies and weeklies, endgame modes, and limited activities. In Covert Commissions, the post-mission selection can include high-value pulls; for example, gold-tier drops such as “10 Thoughts” have a low chance to appear, and you can only take one of the three items each run. Plan for repetition.

Tip: If you’re just getting started, install the game on PC from the Epic Games Store listing for Duet Night Abyss to access these systems and their tutorials: Duet Night Abyss on Epic Games Store.

Where Remanent Reminiscence fits in your build

This sword’s identity is built around charged attack uptime. A 30% chance to preserve Combo Points on charged use means more loops of your heavy hits before you have to rebuild resources. It’s best slotted on characters and playstyles that:

  • Convert Combo Points into high-value charged strings frequently.
  • Benefit from longer windows of uninterrupted burst damage.
  • Don’t rely on elemental interactions from the weapon itself (it’s Neutral) and can instead scale with Crit and personal multipliers.

Demon Wedges that amplify charged attack damage, improve Crit return, or mitigate downtime between charged inputs synergize naturally with this kit. Prioritize wedges that either make your charged hits land harder or reduce the friction to reaching each charged window.


Farming routine for the blueprint and materials

  • Focus on Weapon-category Covert Commissions when the objective is fast to clear for you; objectives rotate hourly, but the reward list tied to your chosen Secret Letter stays the same.
  • Take the Remanent Reminiscence blueprint the first time it appears. After that, always pick the highest-value material you’re short on for crafting or upgrades.
  • Maintain daily Secret Letter Clue income via routine tasks so you can keep rolling Commissions without idle gaps.
Note: Expect variance. Post-mission rewards are a three-item selection from a larger pool, and higher-tier items have lower appearance rates. For weapons specifically, the grind is lighter after the blueprint drop because all remaining materials come from the same activity loop.

Quick reference

Topic Key points
Identity Sword that extends charged attack loops by conserving Combo Points
Core stat lean Neutral element, Spike attack type, strong baseline Crit profile
Unlock path Weapon Covert Commissions → blueprint drop (once) → materials farm → craft
Best fit Charged-attack centric builds; wedges that boost charged damage or Crit uptime

If your roster leans into heavy charged strings, Remanent Reminiscence is an efficient way to stretch each resource bar further. Once the blueprint drops, you’re only a few focused Commissions away from a sword that keeps your burst windows open longer and your damage plan simple: charge, swing, repeat.
