This oil comes in a 0.5-liter clay flask. As an action, you can splash oil onto a creature within 1 sqr. (1.5m) or throw the flask up to 4 sqr. (6m), shattering on impact. Make a ranged attack, treating the oil as an improvised weapon. On a hit, the target is covered in oil. If the target takes fire damage before the oil dries (after 1 minute), it takes an additional 5 fire damage. You can also pour oil to cover a 1 sqr. (1.5m) area on a level surface. If lit, the oil burns for 2 rounds, dealing 5 fire damage to any creature entering or ending its turn in the area.
