Duet Night Abyss Track‑Shift Modules — halve wedge costs with smarter slot matches

Change slot Tracks to match wedge symbols, lower Tolerance costs, and fit higher‑rarity gear on characters and weapons.

Duet Night Abyss Track‑Shift Modules — halve wedge costs with smarter slot matches

Demon Wedges are the core gear layer for both characters and weapons. Each character and each weapon has six Wedge slots, and wedges come in two categories—Character and Weapon—that aren’t interchangeable. Every piece has a fixed stat line per rarity, so the hunt is about collecting the right effects and tiers, not rolling better sub‑stats.

Equipping wedges consumes a capacity called Tolerance. Higher rarity and upgrades add more stats but also raise Tolerance cost. Many wedges show a symbol; if you place one into a slot with the same Track symbol, that wedge’s Tolerance cost is cut in half. Matching Tracks is the most reliable way to fit stronger pieces without busting the cap.

What Track‑Shift Modules do

Track‑Shift Modules let you change a slot’s Track so you can create that symbol match on demand. Flip a slot to the symbol your wedge needs, drop the wedge in, and its Tolerance cost is halved. That single change often frees enough budget to equip a higher‑rarity effect or keep a key wedge upgraded without removing something else.

Character slots and weapon slots use different modules. The item names in your inventory reflect this split, and the two cannot substitute for each other.

How to get Track‑Shift Modules

Source Details Notes
In‑game shop Purchase modules directly Availability can be limited by a monthly cap
Lunosmith crafting Craft after obtaining the relevant blueprint Character and weapon modules craft separately
Leveling milestones Earned by leveling characters and weapons Module type matches the unit you level
Events and rewards Occasional event drops include Weapon Track‑Shift Modules Check active event reward lists

When to use a Track‑Shift Module

Use a module when a single Track match unlocks a clear capacity win. Common cases:

  • You need to slot a higher‑rarity wedge but are just over the Tolerance cap. Matching its Track often halves the cost enough to fit.
  • Upgrading a core wedge pushed your build over budget. Changing the slot’s Track restores headroom without dropping a key piece.
  • You want to consolidate effects by replacing two lower‑rarity wedges with one strong piece. A Track match can make the swap possible.
Tip: Reconfigure Tracks only when the half‑cost outcome actually frees enough Tolerance to change your build. If the saved capacity doesn’t enable a stronger piece or a level breakpoint, save the module.

Why Track‑Shift matters as you progress

As rarities climb from Grey up to Gold, stats and effects rise alongside Tolerance costs. Upgrading wedges further increases those costs. Track matching is the pressure valve that keeps late‑game builds viable: it halves the cost on your most expensive, most impactful wedges, letting you keep the rest of the kit intact. Because Character and Weapon wedges are separate systems with their own caps and modules, you’ll be making Track calls on both sides of the loadout.


Quick reference

Topic Key point
Categories Character wedges and Weapon wedges are separate; their modules are separate too
Slots Six per character and six per weapon; not all are open at the start
Tolerance Equip budget per unit; higher rarity and upgrades cost more
Track match effect Matching a wedge’s symbol with the slot’s Track halves that wedge’s Tolerance cost
Modules Track‑Shift Module (characters) and Weapon Track‑Shift Module (weapons) change slot Tracks
Acquisition Shop, Lunosmith crafting with blueprints, leveling rewards, and occasional event drops

Plan your Tracks around your most expensive wedges. Shift the few slots that unlock half‑cost matches for those pieces, then build the rest of the layout around the Tolerance you free up. That’s the cleanest path to fitting late‑game effects without sacrificing your core kit.
