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 to cast this spell, which disappeared.

History
The spell was invented by the Netherese arcanist Shan in &minus;644 DR.
