Specter Oil
From Witcher Wiki
"There is a mysterious boundary between the worlds of the dead and the living, one which is easier to cross for restless specters than for humans. To injure a spectral opponent, first anoint a blade with this oil. Only then will the weapon truly part the curtain dividing the worlds, thereby damaging the specter."
A blade coated with Specter Oil causes increased damage to specters. Damage inflicted on specters is increased by 100%.
