- Core Mechanic: Modify guns with swappable Weapon Parts to define fire patterns and elements.
- Synergy Key: Match parts to your build category (Shatter, Disruption, Growth) for maximum effect.
- Best Strategy: Prioritize Piercing parts for Shatter and Elemental parts for Disruption.
- Critical Tip: Use Relic Fusion to amplify weapon effects rather than spreading stats thin.
- Top Choice: AoE freeze parts are the strongest for controlling dense bullet-hell waves.
Understanding Weapon Parts
Weapon Parts are the foundation of customization in Pass the Fear. These swappable modifications alter a gun's behavior, changing fire rate, projectile pattern, element, and damage type. Unlike standard loot drops, parts allow you to engineer specific solutions to the Witch's Disaster threats.

The system divides parts into distinct functional categories. Choosing the right combination transforms a basic sidearm into a run-defining tool. For instance, pairing a high fire-rate base with piercing rounds creates a "Shatter" monster capable of tearing through armored bosses, while adding frost modifiers supports "Disruption" builds by freezing hordes in place.
Do not mix random parts. Commit to a specific build category early. If you are playing Explosive Cutie, stack AoE and blast radius parts immediately to leverage her passive talents.
| Part Category | Primary Function | Best Build Synergy |
|---|---|---|
| Barrels | Fire rate, spread pattern | Final Shot, Shatter |
| Ammunition | Damage type, projectile count | Growth, Disruption |
| Elemental Mods | Status effects (Burn, Freeze) | Disruption, Control |
| Stocks | Stability, reload speed | Embarkation, Defense |
| Sights | Range, accuracy, aim assist | Shatter, Final Shot |
Guncrafting by Build Category
Effective guncrafting requires aligning your parts with one of the five main build archetypes. Using parts that conflict with your chosen category results in weak damage and wasted potential. Below is a breakdown of optimal part selections for top-tier builds.
Shatter Build
- Focus: High burst and armor piercing
- Core Parts: Piercing rounds, high-caliber barrels
- Target: Armored elites and bosses
- Synergy: Combines with Critical relics
Disruption Build
- Focus: Crowd control and status effects
- Core Parts: Elemental mods (Frost/Lightning)
- Target: Dense trash enemy waves
- Synergy: Extends status duration via Tarot
Growth Build
- Focus: Scaling damage and resource gen
- Core Parts: Gold-gain mods, multi-shot
- Target: General clearing and economy
- Synergy: Amplifies Team Talents
Crafting rare parts costs significant gold. Save your currency for parts that directly upgrade your damage output or survivability. Avoid cosmetic-only parts until the late game.
| Build Archetype | Priority Stat 1 | Priority Stat 2 | Avoid These Parts |
|---|---|---|---|
| Shatter | Armor Pierce | Crit Chance | Spread / Shotgun |
| Disruption | Status Effect | AoE Radius | Single-target precision |
| Growth | Gold Find | Reload Speed | High recoil / Low accuracy |
| Embarkation | Move Speed | Mag Size | Heavy / Slow parts |
| Final Shot | Execute Damage | Accuracy | Low velocity / DoT |
Step-by-Step Crafting Process
Follow this workflow to optimize your weapon loadout during a run. This process ensures you never waste resources on inferior upgrades.
Identify Your Role
Assess your character and starting weapon. If playing Iron Bucket Knight, prioritize stability and defensive parts. If playing Explosive Cutie, immediately seek AoE modification parts to maximize her blast radius passive.
Scout for Base Weapons
Find a base weapon with high innate stats (e.g., a fast-firing SMG or a high-damage sniper). The base weapon determines the ceiling for your crafted final product. Always check the weapon's compatibility with your chosen build category.
Install Core Modification
Equip your primary modification part. For Shatter, install a piercing barrel. For Disruption, add an elemental capacitor. This part defines the gun's new identity and interaction with relic fusion effects.
Tune with Secondary Parts
Add secondary parts to fix weaknesses. If your gun has high damage but slow reload, equip a lightweight stock. If accuracy is poor, add stabilizing sights. Balance is key to surviving the bullet-hell.
Fuse and Test
Visit the forge to fuse the parts permanently. Test the weapon in the next combat wave. If it fails to melt enemies or control crowds effectively, consider scrapping it for resources rather than sinking more gold into a dead end.
Co-op Crafting Synergy
In online co-op, guncrafting shifts from personal optimization to team role fulfillment. Coordination allows the squad to cover all weaknesses: crowd control, single-target damage, and sustain.
The ideal co-op squad assigns one player to Disruption (Freeze guns), one to Shatter (Anti-armor), and one to Growth (Economy/Support). This overlap ensures every enemy type is countered efficiently.
| Role | Weapon Focus | Recommended Parts | Team Benefit |
|---|---|---|---|
| Crowd Control | AoE / Frost | Freeze mods, Explosive rounds | Locks down waves for team |
| Boss Killer | Single-target | Armor Pierce, High Crit | Melts high-HP targets fast |
| Support | Utility / Healing | Lifelink mods, Buff aura | Increases team survivability |
When swapping items, ensure the receiver's build can actually use the weapon. Giving a precision rifle to a tanky knight with no accuracy talents is less effective than giving it to the One-Eyed Codger. Communicate your part needs in voice chat to avoid duplicate crafting efforts.
Endgame Crafting Goals
To survive the Chaos Battle Scar mode and the final dawn encounter, your guncrafting must reach peak efficiency. Generic parts will no longer suffice against the scaled bullet patterns of the Witch's Disaster.
Chaos Battle Scar Prep:
- Acquire Legendary-tier Elemental Parts
- Unlock 'Master Craftsman' Talent for fusion bonuses
- Craft a dedicated boss-killer armor-piercing sidearm
- Stockpile emergency reload speed parts for panic moments
- Fuse relics to reduce weapon cooldown and ammo consumption
Prioritize Legendary Elemental Parts that trigger chain reactions (e.g., lightning that jumps between enemies). These parts are essential for clearing the massive enemy densities found in late-game loops. Additionally, ensure your defensive build includes parts that grant temporary shields on reload or kill, as dodging becomes nearly impossible in the final stages.
Frequently Asked Questions
Q: Can I dismantle crafted weapons to get parts back?
Yes, you can dismantle weapons at the forge. You will receive a portion of the gold used and sometimes recover the rare Weapon Parts, though legendary parts may have a recovery chance lower than 100%.
Q: Which Pass the Fear build benefits most from guncrafting?
While all builds benefit, the **Shatter** and **Disruption** builds rely most heavily on specific parts. Shatter needs armor-piercing mods to function, while Disruption requires elemental mods to freeze enemies.
Q: Do weapon parts transfer between runs?
No, Weapon Parts are reset every run. You must scavenge and craft new weapons in each attempt to escape the island. However, your knowledge of optimal recipes persists.
Q: How does Relic Fusion interact with guncrafting?
Relic Fusion amplifies the effects of your equipped parts. For example, a fusion that increases 'elemental status chance' directly boosts the effectiveness of the Frost or Lightning mods you attached to your gun.
