Weapons & Parts

Weapons in Pass the Fear are not static loot — they are platforms you reshape with barrels, grips, elemental converters, and trajectory modifiers found in shops, elite drops, and island events. You carry two weapons at all times, and each accepts multiple part slots depending on its base type. A rifle found on floor one can look unrecognizable by floor five if you commit to a build direction early and shop accordingly.

This guide covers how weapons and parts work mechanically. Pair it with Build Basics for slot math and with specific routes like Fireworks Master, One-Shot Nuke, and Dual Element for priority shopping lists.

Base weapon families

Auto rifles offer consistent DPS and accept most general attachments — a flexible default when you do not know your build yet. Shotguns start strong for Fireworks Master because many roll with innate multi-pellet behavior that counts as multiple trajectories for on-hit procs. Charge weapons — railguns, heavy bows, cannons — anchor One-Shot Nuke because their damage compresses into single release events compatible with Final Shot and Growth. Burst pistols and SMGs sit in the middle: excellent secondaries for add clear while your primary handles boss identity.

Elemental identity usually comes from barrels, not the base weapon. A physical auto rifle plus fire barrel is a fire weapon for relic and affix purposes. That rule matters when you read relics that require “fire damage” or “frost on hit” — the barrel defines the tag.

Part categories

Barrels change damage profile, element, trajectory count, and sometimes fire mode. Trajectory barrels add parallel shots or forks — the highest-priority pickup for fireworks routes. Element barrels convert damage type and often extend status duration — mandatory for Dual Element. Charge-mod barrels adjust wind-up time and release damage — hunt these for nuke builds.

Magazines and clips alter magazine size, reload speed, and last-bullet behavior. Last-bullet mods synergize with Final Shot affixes documented in affixes. Reload speed is underrated on every build; dead time is dead damage.

Stocks and grips usually trade stability for mobility or vice versa. Some rare grips add proc chance or crit — worthwhile when your build is otherwise complete.

Special attachments include fusion modules, fragment generators, and shop-only experimental parts. These often carry affix tags directly — a fragment generator might print Fragment without needing a random affix roll on the base weapon.

Affixes on parts

Parts can roll Fragment, Growth, Final Shot, Disruption, Embarkation, and Shatter just like weapons and relics. When a shop offers a part with an affix that matches your build, buy before generic damage upgrades. A mediocre barrel with Fragment outscales a perfect barrel with no tags if you are stacking trajectories. Full affix definitions live in the dedicated affixes guide.

Build-specific shopping priorities

Fireworks Master: trajectory barrel first, fire-rate or reload second, Fragment-affix parts third, element last unless co-op demands it.

One-Shot Nuke: charge or crit barrel, last-bullet magazine mods, Growth-affix grips, avoid split or fork attachments entirely on primary.

Dual Element: dual-element or alternating barrels, status duration attachments, Shatter-affix parts, never mix random-element rolls without a normalizing relic from relics.

Two-weapon loadout strategy

Your primary weapon chases your main build identity. Your secondary covers gaps — add clear, element setup, or boss finisher tech. Common pairs: fireworks primary plus nuke secondary for bosses; dual-element primary plus physical auto secondary for bats; charge nuke primary plus cheap SMG secondary for everything small.

Do not split affix investment across both weapons unless you are deliberately running hybrid tech. Ten relic slots already demand focus; two half-built weapons plus ten scattered relics is how runs die to the first mini-boss.

Shops, drops, and rerolls

Shops refresh between island phases. Elite drops skew toward higher rarity parts with affixes. Some events offer free rerolls or fusion — save currency for trajectory barrels on fireworks runs even if a damage relic tempts you in the same shop window.

Tarot cards from tarot cards can discount shops or boost part rarity — factor them into your economy plan when you pick run-wide modifiers.

Co-op trading

Online co-op allows item exchange in many sessions. Trajectory barrels and dual-element parts are high trade value because they are build-defining. Communicate before swapping — your teammate’s nuke secondary might be your fireworks primary with one part change.

Evaluation checklist

Before equipping a new part, ask: Does it change my element tags? Does it add or remove trajectories? Does it help or hurt Final Shot timing? Does it carry an affix I am stacking? If four answers are “wrong,” pass even if the arrow is green.

Weapons and parts are the foundation every other system stacks on. Get the base platform right — the right barrel on the right weapon for the right build route — and relics plus tarot multiply instead of confuse.
