Consonance weapons in Duet Night Abyss are not just another gear slot. They’re character‑exclusive tools that manifest from a specific skill or ultimate and replace the corresponding equipped weapon for as long as the effect is active. Only characters with a skill that summons a weapon have access to one; if a kit never calls a weapon in, there’s no Consonance weapon to build.

Consonance weapons vs. weapon proficiency

It’s easy to mix up the two systems because they both reference weapon types, but they operate on different layers of a character’s kit:

  • Consonance weapons: bound to a particular character’s skill/ultimate. They appear when that skill is used and disappear when the effect ends. They’re unique per character and can be customized with Demon Wedges.
  • Weapon proficiency: every character has two permanent proficiencies (one melee, one ranged) that determine what they equip outside of Consonance windows.

Examples that highlight the split:

Character Consonance weapon type Melee proficiency Ranged proficiency
Berenica Sword Swords Dual Pistols
Lynn Greatsword Greatswords Dual Pistols
Lisbell Greatsword Greatswords Shotguns
Psyche Polearm Polearms Assault Rifles
Rebecca — Polearms Grenade Launchers
Daphne — Whipswords Assault Rifles
Note: not every five‑star character has a Consonance weapon; only kits that summon one do.

Where to view and equip Consonance weapons

  • Access: find a character’s Consonance weapon in the Archive or the Armoury.
  • Equipping: Consonance weapons accept the same Demon Wedges used by standard weapons.
  • In combat: when you trigger the relevant skill or ultimate, the Consonance weapon takes over the matching slot until the effect ends, then your normal weapon returns.

Demon Wedges on Consonance weapons

Demon Wedges function like modular mods: you collect, craft, level, and equip them onto weapons. Each wedge has a cost, and your total can’t exceed the weapon’s capacity (referred to as tolerance). On Consonance weapons, wedges apply during the skill’s active window, letting you tailor how that summoned weapon hits.

  • Capacity management: balance higher‑cost wedges with lower‑cost picks to stay within tolerance.
  • Stat shaping: wedges can boost attributes such as attack type damage, attack speed, trigger probability, range, duration, or skill damage — match these to the character’s Consonance behavior.
  • Stance changes: some wedges alter attack stance, subtly changing hit timing and range, which can impact practical DPS depending on the kit and encounter.

Ymir (Berenica) — best Demon Wedge loadout and stat priorities

Ymir is Berenica’s Consonance weapon. Her damage window hinges on rapid, reliable hits while the enhancement is active, so the wedge plan emphasizes attack cadence, proc chance, and coverage.

Slot Recommended wedge
Slot 1 Focus
Slot 2 Edge
Slot 3 Threshold
Slot 4 Trammel

Prioritize these stats on Ymir’s wedges:

  • Slash ATK to scale her hit type
  • Attack Speed to pack more strikes into the Consonance window
  • Trigger Probability to proc on‑hit effects more reliably
  • Attack Range to catch more targets per swing
Tip: if you’re up against tolerance limits, drop the least impactful secondary roll before sacrificing core stats or speed.

How to pick wedges for other Consonance weapons

The same logic travels well across the roster: build to the behavior of the summoned weapon window.

  • If the kit deals damage primarily through the Consonance skill, lean into skill damage, duration, and trigger chance to extend and amplify the window.
  • If the Consonance weapon converts basic strings into a heavier hit type, favor the relevant damage type plus attack speed for better throughput.
  • For area control or off‑field effects, range and duration tend to outperform raw attack in real encounters.

The headline to remember: Consonance weapons are brief, high‑impact windows that override your normal slot. Treat them like timed power tools — build wedges that make those seconds count, and in Berenica’s case, Ymir’s Focus/Edge/Threshold/Trammel setup is a clean place to start.
