Weapon Tier

Current player state

Enter your current values before buying Mutation. Fields start at the game’s own default stat block, where every stat but Max HP starts at zero — a 0 here is that default, not an empty field. Player stats use the same device-local values as the weapon pages.

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

One-Armed — +100% normalized signed change (Ranged Damage +1 resolves ×2; Elemental Damage +1 resolves ×2)
Cyborg — +50% normalized signed change (Ranged Damage +1 resolves ×3; Elemental Damage +1 resolves ×0)

Resolved direct-stat change: −50% or less

Builder — −75% normalized signed change (Ranged Damage +1 resolves ×0.25; Elemental Damage +1 resolves ×0.25)
