Pestilence - Hishna

The pestilence spell creates a mild form of insect plague, nowhere near as frightful as the 5th-level priest spell, but far more long-lasting. The pestilence spell summons crawling insects, such as ants, roaches, weevils, caterpillars, and other types of bugs. These creatures will infest the area of effect, devouring plant life and driving animals away. After one day, the area will be picked clean, but the creatures remain for the full duration of the spell.

Creatures within the area of pestilence sustain one hit point of damage per turn (or fraction of a turn) within the area, from the bites and stings of the creatures. The pestilence cannot be moved once it is cast.

The material component is a bit of spider's venom and the husk of a dead June bug.
