Mr. Duncan is a 5-star Beast Afflatus DPS in Reverse: 1999 version 2.2, excelling in counter and riposte mechanics through his unique Bullet system. This build guide optimizes his crit synergy, Reality DMG output, and team bullet sharing for current PvE meta like LP/MA stages as of February 2026. Focus on Psychubes that amplify ripostes, ultimate bursts, and Insight upgrades for team viability.
Skill Overview
Mr. Duncan's kit revolves around Reality DMG with DPS, Reaper, and Riposte tags; his core is generating Acidic/Fragmented Bullets via Makeshift Inventions (S2: gain 2 Bullets + 2 Quick Draw rounds for preemptive counters).
Deadly Ditty (S1): Deals 105-175% Mass Reality DMG + Genesis burst (ATK x90-150%) if enemy HP <50%.
A Veteran's Regards (Ultimate): 500% single-target Reality DMG, gaining +10% Crit Rate per Bullet type consumed.
Swift Riposte from Quick Draw triggers 200-300% preemptive Reality DMG before enemy attacks land.
