Sulfur Game Oils: Modifiers, Stats, and Best Builds

Weapon oils in SULFUR are permanent weapon enchantments that modify damage output, projectile count, recoil control, bullet behavior, and ammo efficiency. Players apply these items to open enchantment slots on ranged firearms to shape specialized combat loadouts across dungeon expeditions.

What Are Weapon Oils in SULFUR?

An oil is an inventory consumable that attaches permanent positive and negative stat modifiers directly to a firearm. Developed by Perfect Random on their official website, the action-adventure extraction shooter features hundreds of distinct oil bottles that drop from dungeon chests, fall from defeated elites, or appear in merchant inventories. Each weapon starts with fixed base statistics and unlocks up to five enchantment slots as its weapon rank increases through combat experience.

Applying an oil consumes the item from your inventory and locks its attributes onto the firearm permanently. Game loading screens confirm that once an enchantment or oil binds to a weapon, players cannot detach it. Inspecting a firearm in the field shows the resulting stat profile, and patch notes indicate players can press L to trigger weapon inspection animations. Before committing rare bottles to your best weapons, evaluate how the stat adjustments interact with the base weapon architecture.

Every enchantment slot filled also impacts weapon wear over time. Each standard oil or scroll socketed onto a firearm increases the durability lost per shot by one point, meaning a gun with five standard modifications consumes significantly more durability per trigger pull than an unmodded weapon. Durability-focused oils like Inherited Oil and physical attachments like muzzle brakes do not add this per-shot penalty.

How Do Weapon Oils Modify Gun Stats?

Stat modifiers on oils alter ballistic handling through direct tradeoffs across six primary performance categories:

1. Damage: Modifiers apply either as flat point additions (+30 flat damage) or percentage multipliers (+50% damage).
2. Projectiles: Multi-pellet oils increase the shot volume per trigger pull at the expense of damage per pellet or wider spread.
3. Recoil and Aim: Heavy recoil reductions frequently require disabling aimed down sight (ADS) entirely.
4. Handling and Reload: Faster cycle speeds and reloads often reduce weapon durability or attack speed.
5. Bullet Physics: Modifiers adjust velocity, penetration depth, bounce frequency, and bullet drop.
6. Economy: Several top-tier utility oils eliminate coin drops or enemy organ drops upon death.

The developer refined more than 150 individual oils and attachment values in the Scholar's Update announcement, altering spread penalties across multi-projectile options and fine-tuning recoil modifiers:

"Many Oils and Attachments should now be more useful across different playstyles." — the developer's Steam announcement

Player testing on the official Steam store page discussion boards revealed that update 1.0 also divides added damage on 12-gauge weapons across the weapon's pellet count. Flat damage oils that once added 30 points to every pellet now distribute that flat sum across all eight standard shotgun pellets, making percentage damage oils significantly more effective on multi-pellet firearms.

Which Oils Provide the Highest Damage Values?

High-tier damage oils are stat-modifying consumables that increase either a flat point value or a percentage multiplier per shot. Choosing the correct damage oil depends on the weapon caliber and starting base damage.

Flat Damage vs Percentage Damage

Percentage damage oils produce higher numerical gains on weapons that possess high single-shot base damage, such as firearms chambered in 50 BMG or heavy revolvers. Slow Punch Oil and Glass Cannon Oil each provide a 50% damage increase. Slow Punch reduces bullet speed by 50%, while Glass Cannon reduces maximum durability by 25%. Pairing Slow Punch with the Holy Fire scroll bypasses the bullet speed penalty, as Holy Fire converts projectiles into instantaneous railgun beams.

Flat rate damage oils provide fixed point boosts regardless of the weapon caliber, making them strong choices for low base damage firearms. Pot Shot Oil adds 35 flat damage while disabling ADS. Acetic Oil grants +30 flat damage while removing enemy coin drops, an inconsequential trade-off given that most soul coin income comes from selling discovered gear. Late Boom Oil adds 30 flat damage at the cost of 30% bullet speed.

Managing Durability and Recoil Trade-offs

Automatic firearms generate severe muzzle climb, especially after converting ammunition types with calibers like 12-gauge or 50 BMG. Stable Hip Oil cuts weapon recoil by 62% in exchange for disabling ADS. Combining Stable Hip Oil with an A12C Muzzle Brake (-35% recoil) or Breznik BMD attachment negates nearly all weapon climb, allowing automatic assault rifles to maintain laser-like precision while hip-firing.

When building specialized gun builds for endless mode, durability management becomes essential. Inherited Oil increases maximum weapon durability by 50% while setting enemy loot drop chance to zero. Because loot chests, breakable containers, and boss payouts remain fully functional, losing standard mob drops poses little threat to run economy.

Ammo conservation builds utilize combinations of no-consume oils to eliminate reloading completely. Pairing Mosquito Oil (40% chance not to consume ammo), Saviour Oil (30% chance), and Tetris Oil (20% chance) drops ammo consumption dramatically. Adding Bulk Oil or parallel magazine attachments allows high-rate-of-fire weapons to sustain continuous fire without cycling through standard reloads.

How Can You Acquire and Apply Oils?

The primary hub vendor for purchasing oils is Kevin, located in the church attic above the central sanctuary. Kevin stocks random assortments of oils and allows players to reroll his inventory for soul coins. Weapon attachments come from Ralphie, while baseline firearms are sold by Stiff Leg in the same church settlement.

Dungeon expeditions offer several reliable methods to harvest oils in the field:

1. Opening red treasure chests hidden throughout Caves, Sewers, Castle, and Town sectors.
2. Defeating area mini-bosses such as Splitter, who consistently drops high-tier scrolls and oils before the stage exit.
3. Breaking cracked walls in Caves using sulfur grenades, rocket scrolls, or explosive sidearms.
4. Purchasing random bulk supplies from wandering merchants like the Haukland salesman found in cave outposts.

Because inventory space remains tight during extraction runs, store desirable damage and multi-projectile oils in your home stash chest between runs. Read all positive and negative lines carefully before applying them, and review can you remove oils to avoid permanently locking unwanted penalty stats onto high-value firearms.
