Once Human Guide | Little Jaws Build

This guide presents the definitive Little Jaws build for Once Human, tailored to excel in Endless Dream and Endless Stream scenarios. 

By exploiting the enhanced Unstable Bomber buff and synergizing calibrations, accessories, weapon pairings, deviations, gear sets, and mods, this build delivers an overwhelming single-target burst and dependable AOE clearance. 

Each section outlines precise configurations and justifications to empower players to capitalize on Little Jaws’ explosive potential fully.

Weapon Overview

The Little Jaws SMG now benefits from a 20% damage buff, making its Unstable Bomber procs exceptionally potent.

Each hit applies an Unstable Bomber effect that detonates after 0.9 seconds, dealing 120% base blast damage at a default radius of 1.5 meters, decaying to 50% over distance. 

Shot procs add a 20% final damage bonus per bullet, while every 0.1s of detonation delay grants an additional 15% damage, yielding a default 45% bonus independent of cradle or mod bonuses.

Unstable Bomber damage is purely elemental, cannot crit or strike weak spots, and does not decay over bullet travel. 

This build leverages Little Jaws’ high single-target damage and augments its AOE capability through a complementary secondary weapon.

Despite higher ammo consumption and reduced effectiveness versus elemental immune foes, the SMG shines against shielded and phase anomaly enemies.

Calibration

Little Jaws needs the Heavy Style calibration so that the clip can hold more rounds, which increases the chances of getting the Unstable Bomber proc per reload.

Due to the build's reliance on Unstable Bomber explosions, substats should favor a double elemental damage bonus.

Accessories

Equipping a Small Break muzzle provides crucial accuracy, while the Compact Reflex Sight optic and Cobra Grip further stabilize recoil.

A Weighted SMG Mag extends sustained fire, maximizing proc uptime. Ammo choice—Blasting AP Ammo, Suppression AP Ammo, or Penetration AP Ammo—should align with content requirements.

Secondary and Melee

Three secondary options offer situational utility. The Hazardous Object excels at AOE, dealing up to 480% blast damage without decay; pair it with Rapid Shot Stock calibration and double elemental damage substats. 

The Gulped Lure grants stacks of 20% Unstable Bomber damage bonus and -10% range per kill (up to five stacks), with ice cubes from Ice Pot Deviation extending or refreshing stacks. 

The Bingo inflicts an 8% vulnerability bullseye on the first hit, enabling potent combos: spawn the Maiden, swap to Bingo, trigger the bullseye, and then fire Little Jaws.

Multiple gear presets facilitate rapid swaps between Hazardous Object, Gulped Lure, and Bingo. 

he Kukri melee weapon delivers heavystrike kills against ice cubes for +20% sign density, further enhancing Unstable Bomber damage.

Deviation

The primary deviation choice is the Shattered Maiden, which stuns standard foes or slows and increases explosion damage taken by 80% on Great Ones.

As a fallback, the Mini Feaster summons tentacles every 1.5 s, each granting a 20% status damage bonus (max 80%).

Key Gear

For singletarget engagements (e.g., Light Dreamer), the Explosive Front Top is optimal, offering 0.3 s Unstable Bomber delay (+45% bonus) and +30% Unstable Bomber damage.

For AOE content (nightmare silos, Deep Dreamers), the Viper Mask increases the Unstable Bomber range and grants a 1% damage bonus per 2% range increase, amplifying Hazardous Object blasts.

Gear Sets

Low HP Preset: Three Treasurous Tides pieces (+50% weapon damage, +50% status damage when HP < 70% and low sanity) paired with two Shelter pieces (+8% elemental damage) maximize burst at reduced survivability. 

Sanity Corrosion Capsules (crafted via Electric Stove) reduce sanity to 0% (60% HP loss) to activate buffs; store ice cubes in SUV (12 slots) and Car (8 slots) for ease of stacking Gulped Lure effects.

High HP Preset: Four Shelter pieces grant up to +30% elemental damage through Deviant Energy stacks, and one Renegade piece provides reload speed. Blackstone is avoided due to the build’s low continuous elemental rate.

Mask Hide

The Lucky Rabbit Fur mask hide yields a +10% elemental damage bonus on hit without requiring crits, demonstrated when idle elemental damage rises from 19.2% to 29.2% after a single noncrit hit.

Food Buffs

When marking enemies, Mixed Fried Hot Dog provides the strongest multiplier. Otherwise, Popcorn (+10% Unstable Bomber damage) ensures consistency.

In low HP builds, Surprise Spring Roll (5–15% elemental damage doubled below 40% HP) can outperform Popcorn if high rolls are achieved. Whimsical Drink delivers +25% status damage, boosting proc effects.

Cradle Perks

Core cradle perks include AntiPhase (SMG and sniper damage, phase anomaly bonus),

Tactical Combo (+15% weapon damage),

Status Enhancement,

Elemental Sense,

Explosive Bonus,

Marked Strike (+20% weakspot damage on marked targets),

Deviant Energy Defense and Tactical Leap (+20% damage vs. any enemy, +10% vs. shields).

Survivability can be increased by substituting Aerial Suppression for Marked Strike.

Suffix and Substats Priority

Weapon and mask mods should use the Unstable Bomber suffix, with linked attributes in the Unstable Bomber Range and Blast Damage Bonus. General attributes should include damage against relevant enemy types. 

Helmet and top mods favour the Lunar suffix for doubled bonuses; pants and boots prefer the Downstar suffix for leveldifference scaling.

Gloves should focus on the status damage bonus as a linked attribute; the remaining stats depend on accessory calibration.

Mods

Little Jaws mods: choose Bombardier Souvenir for extended sustained damage when targets require multiple mags or Supercharged for burst scenarios. Avoid Reckless Bomber and Heavy Explosives.

Gulped Lure uses Supercharged for the continuous bonus; Bingo benefits from Vulnerability Amplifier (+8% vulnerability). Hazardous Object pairs with Reckless Bomber to convert its 8% base crit rate into +4% Unstable Bomber damage. Melee can use any fun mod (e.g., Melee Amplifier).

Helmet Mod: Deviation Expert for increased fire rate and +20% status damage.

Mask Mod: Delayed Blast grants +25% Unstable Bomber final damage per four hits.

Gloves Mod: choose Elemental Overload or Status Enhancement based on current bonuses. 

Shoe Mod: Rush Hour for low HP builds (+4% weapon/status per 10% HP lost), otherwise Covered Advance (+20% weapon/status for 30 s after avoiding damage).

Top Mod: any gold mod with optimal substats.

Pants Mod: Elemental Resonance for AOE, Precision Charge for weakspotreliant bosses, or Abnormal Increase for singletarget, noweakspot encounters.
