Oil of sharpness

Oil of sharpness was a magical substance used to maintain and enhance mundane weapons and armor.

Description
Oil of sharpness appeared as a gelatinous substance, speckled with shards of silver.

Powers
When applied, oil of sharpness granted weapons powers akin to those provided by the enchantment process. The effect lasted anywhere from a matter of minutes, up to an hour's time.

One flask of oil allowed for between three to five applications. Depending on the quality of the formulation, an application granted a weapon anywhere from a +1 to +6 enhancement.

During the early Era of Upheaval, a single flask of oil of sharpness ranged in price from 4,000 to 24,000 gp. As of the late 15 century DR, enough oil for a single application cost a mere 10 gp.
