How players win with One-Armed Community consensus

With a single weapon and doubled modifiers, pick one that handles crowds: Slingshot or Lightning Shiv are the safe choices, SMG for high-roll Ranged Damage runs. Focus and Silver Bullet suit the one-weapon setup; switch to Nuclear Launcher or a legendary when offered.

Stats: Ranged Damage, % Damage, Life Steal, HP Regeneration, Max HP.

Weapons One-Armed boosts most Computed from rules

One-Armed: ordered by how much One-Armed's modifiers raise each weapon's damage compared with a character without modifiers, then by damage per second; weapons One-Armed doesn't boost fall back to raw DPS. Reference profile: One-Armed's own stats plus 20 points bought in the weapon's main scaling stat, both multiplied by One-Armed's modifiers; one weapon, its highest tier, no items, single target, every projectile hits. 89 of 95 equippable weapons scale with a stat One-Armed can raise.

One-Armed's modifiers reward Damage ×2. Restrictions: 1 weapon slot. At the reference profile the highest single-target damage comes from Claw IV (643 DPS).

Damage ×2
Every point from items, level-ups and set bonuses counts ×2; penalties grow by the same factor.

Assumptions and method

  • Damage per hit = round(trunc(base + Σ stat × scaling) × (1 + %Damage/100 + class %Damage/100)); crits average in as chance × round(hit × multiplier). Formulas are datamined from the game code; weapon numbers come from the game-file tables.
  • Cooldown is the tooltip value, which includes the attack animation. Reload weapons average the long cooldown over its shot count. Attack Speed divides the tooltip, an approximation: the game divides only the cooldown frames.
  • Not modelled: pierce, bounce, explosion splash, knockback, on-hit and kill-count effects, structures, and how often the weapon actually reaches enemies. Multi-projectile weapons assume every projectile hits the same target, which favours shotguns.
