Using zero bonus player stats and zero item counters

Chain Gun goes from 65.48 to 164.19 expected primary-target DPS.

Direct DPS change +98.71 DPS +150.7%

The comparison leaves out 1 conditional, temporary, proc, or target-dependent DPS-related effect. No fixed value is substituted for missing combat context.

What the comparison includes

Both sides use the shared expected primary-target, pre-mitigation direct-DPS engine. The after side adds fixed global-stat changes and the declared count/stat-scaled changes shown on this page. It includes staged damage rounding, crit expectation, projectile count, shooting duration, and steady-state mean cooldown.

It excludes enemy armor, target density, positioning, misses, overkill, burning, explosions, spawned attacks, temporary effects without a fixed duration state, conditional procs, target debuffs, and weapon-scripted damage changes. A displayed zero therefore means zero within this stated direct metric, not zero value in every combat situation.

Offer and resolved-stat relationships

Character-specific relationships

Filtered normal rolls

This item is filtered out of normal pre-final shop and crate rolls for the characters below. At the final-wave boundary and in endless, character filters are disabled. If filtering empties the candidate pool, generation can use an unfiltered backup pool. Upgrade rejection stops after 50 retries. These are offer filters, not ownership or use prohibitions.

Bull — listed directly in the character filter
Pacifist — included through Engineering

For declared direct stat effects, the same item calculation used on character pages applies each character’s stat-gain factors. A value group appears when the signed change is at least 50% of this item’s total absolute direct-stat magnitude.

Resolved direct-stat change: +50% or more

Builder — +57.1% normalized signed change (Engineering +5 resolves ×1.5; Ranged Damage −2 resolves ×0.25)

Resolved direct-stat change: −50% or less

Cyborg — −110.7% normalized signed change (Engineering +5 resolves ×0.25; Ranged Damage −2 resolves ×3)
