Duet Night Abyss has launched with a simple promise: all characters and weapons are free to unlock. That no-gacha structure changes how you plan your roster—1.1 is already on the horizon with new arrivals, and smart early investments will carry straight into the update.

Install and first steps (Android)

On Android, install the game from the Google Play listing to get started: Duet Night Abyss on Google Play.

The fastest path to core systems is straightforward: push the main story first. That unlocks your hub, more modes, and several characters. Early on, funnel materials into a single carry until roughly level 40; this stabilizes your runs while you learn boss patterns and unlock progression nodes.

How unlocking works (no character gacha)

Every character can be earned for free. You gather 30 “thoughts” for a character to recruit them, with thoughts awarded through story, modes like Covert Commissions, events, and limited shop purchases. Outfits can be tied to event challenges and weekly modes.

Example: Psyche is obtainable through Covert Commissions and purchasable in the shop. An outfit for her can be earned via Immersive Theatre through November 25 and afterward through a weekly mode. None of these are time-limited unlocks for the character itself.

Best early DPS and support picks (launch meta)

Because the full roster is earnable over time, the question isn’t who you can pull—it’s who deserves your first resources. These kits stand out at launch:

  • Psyche (DPS): Burst carry that trades HP for a powerful ultimate. Scales well with CRIT and can take to the air to avoid melee pressure.
  • Rebecca (DPS): Safe, high-uptime area damage through persistent summons. Scales with Intron upgrades that expand summon count and passives.
  • Lisbell (DPS): Combo-focused heavy attacks with strong stunlock potential once her loop is rolling.
  • Yale & Oliver (DPS): Aerial bomber that punishes clustered mobs from relative safety.
  • Lynn (DPS): Channel-based output that spikes with proper positioning and Laceration stacks.
  • Phantasio (DPS): Stack and window-driven bursts; excels when you can line up Bestial Fury timings.
  • Daphne (Support): Reliable healing, control, and team buffs/debuffs—easy fit in almost any team.
  • Truffle & Filbert (Support): Mobile, consistent healing that works for both farming and bosses.
  • Randy (Support): Shields and defensive tools that stabilize aggressive DPS lineups.
  • Tabethe (Support): Control-leaning support whose value rises in content where crowd manipulation matters.
  • Lady Nifle (Support/Debuff): Debuff-centric pick that shines in specific comp plans.

For a low-risk start, pair Rebecca or Yale & Oliver with Daphne or Truffle & Filbert. Prefer a higher ceiling? Build Psyche or Lisbell and add a stabilizing support.

Free characters you can secure early

Character How to get
Berenica Pre‑registration reward
Rebecca In‑game mail after unlocking Sanctuary
Outsider Story progression
Daphne Story progression
Margie Story progression
Truffle & Filbert Complete “Go, Geniemons!” and the “Covert Commissions” tutorial
Lisbell Misty Maze content
Tip: Build a balanced trio from these free picks while you work toward your long-term favorites. A lineup like Rebecca or Yale & Oliver plus Daphne or Truffle & Filbert will comfortably clear most early content.

Why Intron level shifts rankings

Intron upgrades add passives and streamline core loops, moving some characters up a tier once key nodes are unlocked.

  • Rebecca: Additional simultaneous summons and stronger passives boost sustained AoE and objective defense.
  • Lisbell: Faster combo point generation shortens downtime between empowered heavy attacks.
  • Margie: Gains comfort with progression but remains gated by Jackpot stack needs, keeping her niche.
Note: If a character feels underwhelming at Intron 0, reassess after unlocking their defining passives—several kits only “click” once those are active.

Duet Night Abyss 1.1 characters and timing

The next wave is already scoped: the first major update is slated to feature Zhiliu, Fushu, Yuming, and Kezhou. Fina lands earlier on November 25 as a post-launch addition, with Hilda planned after 1.1.

Character Window Notes
Fina Nov 25 Lumino support with debuffs and notable damage potential; available via Covert Commissions and shop
Zhiliu Version 1.1 Part of the first major update lineup
Fushu Version 1.1 Part of the first major update lineup
Yuming Version 1.1 Part of the first major update lineup
Kezhou Version 1.1 Part of the first major update lineup
Hilda After 1.1 Planned for a later patch

Expect rankings to shift as these kits arrive and balance changes settle. The no-gacha model means there’s no penalty for waiting to see how they perform before committing resources.

What to do before 1.1

  • Finish the main story chapters needed to unlock your hub, Sanctuary, and core modes.
  • Secure early freebies: Rebecca (mail after Sanctuary), Daphne and Margie (story), Truffle & Filbert (Go, Geniemons! + Covert Commissions tutorial), and Lisbell (Misty Maze).
  • Choose one carry (Psyche, Rebecca, or Yale & Oliver are safe bets) and advance them to a comfortable level and Intron breakpoint.
  • Unlock and start running Covert Commissions regularly to target character thoughts, weapons, and Demon Wedges while you prep for Fina and the 1.1 roster.

Bottom line: treat launch as your runway. Build one reliable DPS with a strong support, scoop up the free characters as you progress, and let Intron upgrades round out your favorites. With 1.1 bringing Zhiliu, Fushu, Yuming, and Kezhou—and Fina arriving on November 25—you’ll have new options soon without any pressure to gamble for them.
