Duet Night Abyss: Skill Modifiers Beat Proficiency

A common early assumption in Duet Night Abyss is that matching weapon proficiency yields the best results for any character. In practice, ability-focused builds gain substantially more from global stat lines such as Skill Damage, Skill Duration, and Skill Range. These modifiers apply across all skills and ultimates, not just basic attacks, making several “stat stick” weapons unexpectedly top-tier for theorycrafters optimizing throughput.

Why Proficiency Lags Behind

Weapon proficiency raises the attack value when a character equips a matching weapon class, but this bonus primarily enhances direct weapon attacks. Skill and ultimate damage—which dominate encounter DPS in higher trials—rely on separate multipliers. A modest proficiency bump often cannot match the multiplicative returns of always-on skill modifiers. As content scales, the gap widens: flat attack stacking falls off while Skill Damage, Duration, and Range continue to amplify every ability use.

Global Skill Modifiers: What They Do

Skill Damage explicitly increases the damage, buffs, and debuffs produced by any skill or ultimate. Skill Duration extends the uptime of ability windows, allowing more hits and safer rotations. Skill Range expands coverage, enabling better positioning and area control. Mixing Skill Duration with Skill Damage yields consistent gains because longer uptime translates directly into more total damage within a rotation, improving both throughput and reliability.
