Starting out in Duet Night Abyss and wondering how to unlock every character? Unlike traditional RPGs, this game doesn’t rely on a gacha system. Instead, it uses a shard-based and exploration-driven progression, where players collect Secret Letters and Character Shards to unlock new units. This guide covers every method to obtain characters — from free rewards and story unlocks to farming shards efficiently, along with tips on who to prioritize first.
How Character Unlocking Works in Duet Night Abyss
Duet Night Abyss follows a Warframe-like system, meaning every character can be unlocked through gameplay without spending real money. Here’s how it works:
- Each character requires a certain number of Character Shards (typically around 30) to be unlocked.
- Secret Letters act as keys that tell you which dungeon drops shards for specific characters.
- Shard drops are RNG-based, meaning some runs may not reward any shards at all.
- New characters are added roughly every 28 days, and once introduced, they’re placed in permanent dungeons — no limited-time exclusives.
Some characters, however, can be obtained instantly through quests, events, or story progression.

Farming Secret Letters and Character Shards
Once you’ve unlocked your free characters, it’s time to start farming shards for others. Here’s how to do it effectively:
- Target the right dungeon. Each character’s shards drop in a specific dungeon. Check the in-game info before starting.
- Prioritize “Slaughter” or “Kill All” commissions. These missions are faster and great for farming in bulk.
- Bring strong AI companions. Rebecca (Hydro AoE) and Hellfire (AoE + Taunt) are perfect for clearing enemies quickly.
- Equip wedges that boost drop rate or clear speed. Faster runs mean more chances for shards.
- Repeat runs regularly. Since shard drops are RNG-based, consistency is key.
- Watch for events and shop deals. Some events provide Secret Letters or shard drop bonuses.
Character Dupes and Power-Ups
Dupe copies exist in Duet Night Abyss, but they’re not pay-to-win elements. Certain modes, such as Misty Maze, give duplicate characters like Lisbell. Dupes simply increase potential or boost stats, so don’t worry if you don’t get them immediately. Every character can be farmed again later.
Who to Farm First – Recommended Priority List
Not sure who to aim for first? Here are the best characters to prioritize early in your journey:
- Rebecca – Free and extremely efficient for farming mobs and dungeon clears.
- Hellfire – Great AI companion with AoE damage and taunt; ideal for bosses.
- Lisbell – High DPS potential; great for manual players who like fast-paced combat.
- Truffle & Filbert – Solid duo for exploration and resource farming.
- Randy / Tabethe / Phantasio – Good late-game picks for tanking or boss fights.
Focus on one core character and two reliable AI partners to speed up shard farming.
Tips and Mistakes to Avoid
- Don’t waste time chasing dupes early on. Focus on unlocking new characters first.
- Use Slaughter commissions for AFK-friendly farming with well-equipped AI companions.
- Shard drops can vary — stay patient and consistent.
- Some characters are locked behind story progress, so advance the main quest to unlock new dungeons.
- Join events regularly to get free Secret Letters and bonus drops.
Unlocking every character in Duet Night Abyss is a matter of strategy, patience, and planning — not luck. The absence of gacha makes the process fair and rewarding, giving every player equal opportunity to build their dream team.
Start by claiming all free story and event characters, then move on to farming shards for your preferred picks. With consistency and the right companions, you’ll gradually fill your roster and dominate Atlasia on your own terms. Duet Night Abyss proves that RPG progression can be fun and skill-based — where every unlock feels earned, not bought.
