Grease

Grease (originally called Shan's tallow ) was a low-powered conjuration spell of the creation subschool used by arcane casters to cover a solid surface in an oily film. Some clerics of Ghaunadaur, Ilsensine, Laogzed, and Moander were granted the power of grease by their deities, and ooze genasi could create a similar effect.

Effects
This spell would coat a single object or a ten-foot-square surface within a close range with a layer of slippery grease, which would last for a number of seconds depending on the power of the caster.

Components
In addition to verbal and somatic components, the caster required a piece of butter or a bit of pork rind, although any similarly greasy substance could in theory be substituted. This material component disappeared as the spell was cast.

History
The spell was invented by the Netherese arcanist Shan in.
