For more information regarding oils, see the oils category.
- Formulae with 3 ingredients or those with 4 ingredients require a high or top quality base
- Formulae with 5 ingredients require a top quality base.
- The creation of sword oils (coatings) requires the Oil Preparation skill.
- All oils have a duration of 24 hours, or "long".
- Only one oil can be applied per sword at a time. The effects do not stack. Using a new oil on a sword will replace any current oil and its corresponding effects.
- Unlike potions or bombs, there are no standard quality bases for oils.
- Despite its in-game description, Dog Tallow is considered a top quality base.
Italic text in Effect column reflects the in-game text whilst mousing over a sword to which an oil has been applied.
|Brown Oil||Brown Oil accelerates bleeding; creatures lacking a circulatory system are immune to its effects. Considerable chance of causing Bleeding in foes with every hit.|
|Crinfrid Oil||A blade coated with this substance causes crippling pain to a wounded creature; creatures which do not feel pain are immune to its effects. Considerable chance of inflicting Pain on foes with every hit.|
|Hanged Man's Venom||This blade coating poisons wounded opponents, yet it is ineffective against monsters whose physiology differs greatly from that of humans. Considerable chance of Poisoning foes with every hit.|
|Mystery oil||unknown||Eliminates corrosion and improves low quality blades. Found (not reliably) in the kikimore queen's lair (on her body?), on the werewolf's body, on Azar Javed's body, in a chest in the old mine and in the trunk in the striga's chamber. Testing performed on said low-quality weapons such as the Rusty Sword have yielded no results.|
Oils for monsters
Silver is more effective than steel against the creatures that these oils are intended for, though they can also be used on steel swords.
|Argentia||Witchers coat their silver blades with Argentia, which increases the effectiveness of silver, but weakens steel blades. Damage inflicted increased by 60% (silver sword); Reduced Damage incurred (steel sword).|
|Insectoid oil||A blade coated with this substance inflicts increased damage on all insectoid creatures. Damage inflicted on insectoids increased by 100%.|
|Necrophage oil||A blade coated with this substance inflicts increased damage on necrophages. Damage inflicted on necrophages increased by 100%.|
|Ornithosaur Oil||A blade coated with this substance inflicts increased damage on ornithosaur. Damage inflicted on ornithosaur increased by 100%.|
|Specter oil||A blade coated with this substance inflicts increased damage on specters. Damage inflicted on specters increased by 100%.|
|Vampire oil||A blade coated with this substance causes increased damage to all types of vampires. Damage inflicted on vampires increased by 100%.|
These blade coatings actually harm your blade, so beware!
|Detrimental oil||any other combination||This oil would likely be labelled "unknown oil" until you used it, at which point your blade will be weakened for 24 hours (or until you apply new oil).|
Effects (below medallion) was described as Argentia when applied to steel sword. Same description when applied to the silver sword, which can be quite confusing, as actual Argentia would buff it.
