If you’ve been grinding Duet Night Abyss (DNA) for hours and want to power up your characters with the most broken setup possible, the Prime Serenity Demon Wedge is something you need to farm immediately. It’s easily one of the best Demon Wedges in the game right now — capable of turning sanity regeneration into a powerhouse mechanic that changes how you play every character, especially Rebecca.
Why Prime Serenity Is So Powerful
Normally, every character in Duet Night Abyss regenerates 3 Sanity every 3 seconds. That’s fine early on, but as you reach higher-level enemies or want to spam more abilities, it becomes a serious bottleneck.
Prime Serenity changes that entirely. At just +5 enhancement, it adds +7 extra Sanity regeneration every 3 seconds for you and your teammates. That means instead of 3, you’ll now regenerate 10 Sanity every 3 seconds — over three times faster than normal.
This buff allows characters like Rebecca to unleash their abilities non-stop. For example, her jellyfish summon can now be spammed almost endlessly since you’ll regain Sanity much faster than before.
Stat Bonuses:
- Attack, HP, and Defense boosts
- +7 Sanity restoration every 3 seconds
- Works for all elements (requires the right elemental variant)
How to Get Prime Serenity
Step 1: Reach Level 55 in Noctoyager Manual
You’ll first need access to Level 55 content in the Noctoyager Manual, which unlocks high-tier Demon Wedges like Timeless Prime Serenity.
- Keep progressing through the story and upgrading your equipment until you unlock this stage.
Step 2: Target the Right Elemental Version
Each Prime Serenity wedge is tied to an element.
- Make sure you farm the specific elemental type that matches your main character.
- Example: If you’re using a Fire-based character, get the Fire version of Prime Serenity.
Step 3: Farm Commissions and Bounty Missions
There are two main farming routes to get the wedge and its blueprints:
Noctoyager Manual Missions
- Complete missions within this manual for standard drop rates.
- Using Extra Commission Manuals increases your bonus drops.
Bounty Commissions (Chase Demon Wedges)
- This mode drops blueprints for Prime Serenity.
- You’ll need these blueprints to craft the higher-tier (5-star) version.
Step 4: Craft the Gold-Tier Version
Once you have the blueprints:
- Collect 3 copies of the lower-tier Prime Serenity Demon Wedge.
- Head to the Crafting Station and use the blueprint to forge the gold-tier version.
This 5-star version gives maximum stat bonuses and faster sanity regen.
Step 5: Equip and Optimize Your Setup
- Replace Prime Morale or Prime Resolve with Prime Serenity on your main or support character.
- Equip it on Rebecca or any sanity-heavy unit to maximize uptime.
- If you want to keep your main rod setup for damage, you can assign Prime Serenity to a support character in your tactical backpack.
Before starting a mission, disable Auto Summon. Manually summon your support character with Prime Serenity once inside the mission — this activates the sanity regen bonus instantly.
The Prime Serenity Demon Wedge is a game-changer in Duet Night Abyss. It completely eliminates sanity management issues and allows near-endless ability usage. Whether you’re playing solo or co-op, this wedge should be at the top of your farming list.
Rebecca, the MC, and nearly every other character benefit massively from it — making it arguably the strongest Demon Wedge currently available. If you’re serious about pushing harder stages or boss fights, build this now and see how dramatically your gameplay changes.
