Quick Answer
Choose projectile oils for burst, Aftershock for crowds, ammunition-saving oils for economy, and Cryo Snakes for bosses. Gemini Oil + Add Damage Oil adds projectiles; Plop Back Oil + Saviour Oil reduces ammunition consumption. Your best setup depends on which penalties your weapon can handle.
Which enchantments should you choose for each job?
Choose by purpose: extra projectiles, group control, ammunition conservation, or an effect that can damage bosses.
| Your purpose | Combination, benefit, and cost |
|---|---|
| Projectile burst | Gemini Oil + Add Damage Oil: Projectile Amount +100%, Damage -15, Spread +0.7. More projectiles do not guarantee more damage. |
| Crowd damage | Chain Lightning + projectile or bouncing oils spreads damage while you target one enemy. Base trigger chance: 35%. Oil penalties depend on your choice. |
| Crowd control | Aftershock + bouncing or penetration effects creates more stun opportunities. Trigger chance: 10%; stun duration: 5 seconds. Oil penalties depend on your choice. |
| Ammunition saving | Plop Back Oil + Saviour Oil: Ammo consume chance -50%, Recoil +125%, Loot Chance -100%. |
| Boss damage | Cryo Snakes can damage bosses. |
| Larger explosions | Increased Bullet Size + an explosive Scroll enlarges its Area of Effect. |

Which combo should you use for burst?
Try Gemini Oil + Add Damage Oil when your burst setup needs extra projectiles and can tolerate lower Damage.
Gemini Oil gives Damage -30, Projectile Amount +100%, and Spread +0.7. Add Damage Oil contributes Damage +15. Together, you retain Damage -15 and the full spread penalty.
You are buying more projectiles rather than removing every weakness. The remaining Damage penalty matters when deciding whether this combination suits your gun.
For explosive setups, increased Bullet Size enlarges the explosion proportionally. It also enlarges pools; reducing Bullet Size shrinks these effects. This makes size useful for coverage, without establishing a universal burst-damage winner.

Which oil and scroll combinations clear crowds?
Use Chain Lightning for spreading damage, or Aftershock with bounces or penetration for group stuns.
Chain Lightning suits moderate- or low-damage weapons with high RPM or multiple projectiles. You can focus on a priority enemy while nearby enemies take damage and suffer interruptions. Its base trigger chance is 35%, so you should not expect every hit to trigger it.
Aftershock favors the same high-hit-frequency weapons, but emphasizes control. Its 10% trigger chance can produce a five-second area stun. Impacts near enemies can trigger it without directly hitting an enemy.
Bouncing Oils work especially well for close-range room clearing with many pellets or high fire rates. Penetration and bounces give Aftershock more opportunities to affect a group.
When you combine both effects, eligible surfaces are penetrated first, up to your penetration limit. Hard surfaces cause bounces; other surfaces can cause bounces after that penetration limit.
Least Resistance offers another pairing with bounces or penetration. Its homing can continue afterward, but does not always work reliably. Compare the best scrolls for your weapon if you need damage, control, or homing.
Which combo saves ammunition?
Use Plop Back Oil + Saviour Oil for Ammo consume chance -50%, accepting recoil and loot penalties.
Plop Back Oil supplies Ammo consume chance -20% and Recoil +125%. Saviour Oil adds Ammo consume chance -30% and Loot Chance -100%.
Higher RPM makes recoil accumulate faster on automatic weapons. Slower firing gives recoil more time to recover, which can make this penalty easier to manage.
Ammunition-saving effects usually take priority when extra-ammunition effects trigger simultaneously. Single-loading weapons and weapons firing once per reload are exceptions. Their extra ammunition still comes from reserves, even when ammunition saving triggers.
Chance to not consume ammunition gains nothing above 100%. You should stop stacking that benefit once it reaches its useful limit.
Which enchantments should you consider for bosses?
Consider Cryo Snakes for boss damage; choose Railgun effects when you need to bypass an oil's bullet-speed penalty.
Cryo Snakes can hurt bosses.
Holy Fire, Thunderbolt, and Toxic Lobotomy provide Railgun effects. They replace projectiles with instantly arriving beams or lightning, ignoring bullet speed. This gives you a specific way to compensate for a speed penalty.
That interaction does not establish a universal best boss setup. Choose it for the penalty it solves, then consider your remaining weapon costs. Use the weapon builds page when choosing a gun around your intended enchantment behavior.
FAQ
You should choose enchantments by their job and remaining penalties, rather than treating one combination as universally strongest.
You get Projectile Amount +100%, Damage -15, and Spread +0.7. Add Damage Oil only partially offsets Gemini Oil's Damage penalty.
Plop Back Oil + Saviour Oil gives Ammo consume chance -50%, Recoil +125%, and Loot Chance -100%.
Choose Chain Lightning for spreading damage and interruptions. Choose Aftershock for area stuns lasting five seconds.
Its homing can persist after piercing or bouncing. You cannot rely on it working every time.
