Oil of sharpness

Oil of sharpness, sometimes called oil of honing, 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. Some believed that the oil was derived from the echoes of old battles.

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.

History
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.
