Oil of Holiness

When applied to a weapon, that weapon deals +3 Damage on successful attacks vs. Evil monsters.

Oil takes one round to apply to a weapon. Once applied, the effect lasts for the entire combat.

A polymorphed character can only benefit from a weapon oil if the oil was applied to their weapon prior to transformation. Monks cannot apply a weapon oil to their bare hands but can apply a weapon oil to a physical weapon they wield.

A single weapon may be coated with more than one oil at a time, but unless otherwise specified, each oil takes one round to apply. Multiple coatings of the same oil do not increase that oil’s effectiveness.
