Superior Wizard Oil is a potion that is applied to a weapon. When applied, the weapon will increase the user's spell power by 42. Blizzard did not release a new version of Wizard Oil for high level weapons in patch version 3.0.2 and this potion will not apply to most high level weapons obtained in Northrend. Wizard Oils have been discontinued along with Sharpening Stones for raiding beyond level 70.[1]
