Demon Wedges are vital equipment in Duet Night Abyss, serving as a key method to enhance your characters and weapons beyond their base stats. They come in two types: Character Demon Wedges and Weapon Demon Wedges, which cannot be interchanged but can be shared among characters or weapons of the same type.
How to get Demon Wedges in Duet Night Abyss
Most Demon Wedges are earned by completing commissions found in the Noctoyager Manual within the Combat menu. These commissions vary in difficulty and rank, with higher-level challenges rewarding higher rarity wedges. Other ways to acquire Demon Wedges include boss fights, quests, events, and crafting using blueprints.

Demon Wedges appear in five rarities: Grey, Green, Blue, Purple, and Gold. The Gold rarity is unique as it requires collecting blueprints via special commissions and crafting them.
How to equip Demon Wedges in Duet Night Abyss
To equip Demon Wedges:
Open the Armoury from the menu and elect the desired character.

Click the "Demon Wedges" button.
Drag Demon Wedges to slots or use the Quick Equip feature.
Each character and weapon has six Demon Wedge slots that unlock with leveling. You can’t exceed their Tolerance cap, which limits the number and rarity of wedges equipped. Tolerance increases with level, and wedges from the same set can lower tolerance cost.

How to upgrade Demon Wedges in Duet Night Abyss
Upgrading Demon Wedges requires Coins and Carmine Globules. The maximum upgrade level depends on the rarity:
| Rarity | Max Upgrade Level |
|---|---|
| Grey and Green | +3 levels |
| Blue and Purple | +5 levels |
| Gold | TBD |
Mastering Demon Wedges by farming, equipping, and upgrading them is essential for maximizing your team's power in Duet Night Abyss. They offer fixed, reliable stat boosts that scale with your characters and weapons, helping you challenge tougher content and maintain competitive builds.
