Adaptive Oil

This exotic oil magically changes its effects to exploit your opponent’s weaknesses. Over the course of 1 minute, you can coat one weapon or ten pieces of ammunition with the oil. Once applied, the oil retains potency for 8 hours. A weapon or piece of ammunition coated with the oil counts as magical and when you hit a creature that has vulnerability to a damage type using it, the attack deals that damage type.
