Plague Shot

You imbue several pieces of siege weapon ammunition with an infectious disease that can bring an opposing force low over time. Once the ritual is successfully concluded, the affected pieces of ammunition glow a sickly green and must be launched within the hour or the enchantment fades. In addition to its normal damage or other effects, a successful attack with a piece of the affected ammunition exposes every creature within a 60-foot-radius emanation from the point of impact to siege sickness.
