Midnight Oil

Substance, common

This oil is identical to a flask of oil, but possesses additional properties.

• When thrown, you must make an attack roll against any creature within 5 feet of the original target to determine if they’re also covered in oil.
• When poured, the oil fills a 15 foot square and creates difficult terrain.
• When burned, a fire is created for a number of rounds equal to twice the user’s Intelligence modifier (minimum 2).
