Arsonist build

How players win with Arsonist Community consensus

Summarised in our own words on 13 November 2026; check the patch date of each source against PC 1.2.

Weapons Arsonist boosts most Computed from rules

Arsonist: ordered by how much Arsonist's modifiers raise each weapon's damage compared with a character without modifiers, then by damage per second; weapons Arsonist doesn't boost fall back to raw DPS. Reference profile: Arsonist's own stats plus 20 points bought in the weapon's main scaling stat, both multiplied by Arsonist's modifiers; one weapon, its highest tier, no items, single target, every projectile hits. 14 of 95 equippable weapons scale with a stat Arsonist can raise; 81 scale only with Melee Damage or Ranged Damage or Engineering, which Arsonist keeps at 0.

Ranged Damage ×0

Always 0, whatever you buy: items adding it are wasted.

Engineering ×0

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.
