Oil of Slipperiness

A thick, viscous oil that grants the effects of a Freedom of Movement spell for 8 hours when applied. Alternatively, it can be poured on the ground to create a 10-foot square slick area that functions as difficult terrain.

Known supplies:

• One extracted from the saliva of the Roper defeated during the sea cavern climb (Session 7)
• One from the desert hermit Grit's collection, given to Kouzlo (Session 12)
