For more information regarding oils, see the oils category.
- The creation of sword oils (coatings) requires the Oil Preparation attribute.
- 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.
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 silver swords
Except for Argentia, these oils can also be used on steel swords, it is simply preferable to use a silver sword against the creatures for which they are intended.
|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).|
