In Duet Night Abyss, Demon Wedges are the backbone of every build. They slot into both characters and weapons, add flat and percentage stats, and unlock key effects that keep damage scaling into the late game. They’re fixed‑stat pieces—no sub‑stat rolls to chase—which makes the system readable and far less punishing than typical RNG gear grinds.

What Demon Wedges are (types, slots, sharing)

Demon Wedges come in two categories and they are not interchangeable:

  • Character Demon Wedges
  • Weapon Demon Wedges

Any character can use any Character wedge, and any weapon can use any Weapon wedge, provided it’s the correct category.

Each character and each weapon has six Demon Wedge slots. Not all slots are open at the start; additional slots unlock as you level that character or weapon.

Stats on a given wedge piece are fixed. If you pick up the same piece again at the same rarity, it will have the same stat line. The chase is about getting the right pieces and rarities, not rolling better sub‑stats.

Rarity tiers and what changes

Wedges are available in five rarities: Grey, Green, Blue, Purple, and Gold. Higher rarities grant more stats and stronger effects, but they also cost more Tolerance (the system’s capacity budget). Gold is the top tier and is handled differently from the rest—you craft it from blueprints rather than looting a finished piece.

Tolerance, Tracks, and Track‑Shift Modules

Tolerance is the cost to equip a wedge. Each character and weapon has a Tolerance cap, and each wedge consumes some of that cap. As you upgrade a wedge, its Tolerance cost increases, so you have to balance power against capacity.

Each slot has a Track symbol, and many wedges have a matching symbol. Place a wedge into a slot with a matching Track, and that wedge’s Tolerance cost is cut in half. This is the single most impactful way to squeeze high‑rarity pieces into your build without exceeding the cap.

If your slots don’t match the wedges you want to run, Track‑Shift Modules let you change a slot’s Track. Character slots and weapon slots use different Track‑Shift Modules. You can acquire these modules from the shop, by crafting them at the Lunosmith after obtaining a blueprint, and by leveling characters and weapons.

Where to get Demon Wedges (early to late game)

The most reliable source is the Noctoyager Manual under Commissions in the Combat menu. These combat stages reward Character and Weapon wedges and scale by recommended level—higher tiers drop higher‑rarity pieces and effects. As you raise your progression (Trial EXP), more stages unlock, including late‑game tiers.

  • For routine farming, focus on Noctoyager Manual stages at your current power. Level 40 commissions are a practical entry point for consistent wedge farming.
  • Additional sources include quests, boss encounters, and time‑limited events.
  • Bounty Commissions offer weekly targets for high‑end wedges; expect limited weekly pickups for specific “Legendary” targets.
Tip: When browsing Noctoyager rewards, check each wedge’s “Suitable for” tag to confirm whether it’s for characters or specific weapon classes.

Gold wedges are crafted, not dropped

Gold is a blueprint tier. You’ll gather blueprints, then craft the finished wedge at the Lunosmith in Sanctuary. Blueprint sources include:

  • Covert Commissions triggered by using Secret Letters purchased from the shop. Rewards are random from the selected Letter’s pool; a Gold wedge blueprint is one possible outcome.
  • Chase targets in Bounty Commissions.
  • High‑level Noctoyager Manual stages (late tiers, including levels 70–80).

Once you have a blueprint, visit the Lunosmith to craft the wedge. Expect to supply materials and, in some cases, lower‑tier wedges as components.

Upgrading wedges (costs, caps, and trade‑offs)

Open the Armoury, select a wedge, and choose Upgrade. Upgrading consumes Coins and Carmine Globules. Both are farmable via Commissions in the Combat menu. Each upgrade step increases the wedge’s Tolerance cost; high levels can force you to adjust Tracks or swap pieces to stay under the cap. Upgrade caps are tied to rarity, with higher rarities allowing higher max levels.

Practical loop:

  • Level the wedges that drive your build’s core damage or uptime first.
  • Use Track matches to counter rising Tolerance costs as those key wedges climb.
  • Add Track‑Shift Modules to reconfigure slots only when a half‑cost match frees enough budget to fit a stronger piece.

When to start farming in earnest

Early on, wedges are helpful but not critical. Once your baseline damage starts to flatten, shift time into Noctoyager and Bounty Commissions. That’s when the fixed‑stat, Track‑matched loadouts begin to outpace basic level scaling.

Quick reference

Topic Details
Categories Character wedges and Weapon wedges; not interchangeable; shared within their category across characters or weapons.
Slots Six per character, six per weapon; additional slots unlock as you level that unit.
Rarities Grey, Green, Blue, Purple, Gold; higher rarity = more stats and effects, higher Tolerance.
Stats model Fixed stats per piece per rarity; no sub‑stat rolls.
Tolerance Equip cost per wedge; builds must stay under each character/weapon’s cap.
Tracks Match wedge symbol to slot symbol to halve that wedge’s Tolerance cost.
Track‑Shift Modules Change a slot’s Track; character and weapon modules are different; obtain from shop, Lunosmith crafting (with blueprint), and leveling.
Farming Commissions → Noctoyager Manual for steady drops; plus quests, bosses, events.
Weekly targets Bounty Commissions rotate specific high‑end wedges with weekly limits.
Gold wedges Blueprints from Secret Letter Covert Commissions, Chase bounties, and late Noctoyager tiers; craft at the Lunosmith.
Upgrading Costs Coins and Carmine Globules; Tolerance cost rises per level; rarity sets the level cap.

The wedge grind in DNA rewards planning. Fixed stats remove roll anxiety, Tracks cut Tolerance in half when matched, and gold blueprints give you a final, deterministic path to best‑in‑slot. When damage starts to dip, pivot into Noctoyager and Bounty Commissions and build around Track matches; it’s the cleanest way to push into late‑game tiers.
