Ear Seeker (Infestation, Vermin)
Ear seekers are small, maggot-like creatures, brown or white in color. They are found lairing in rotting wood or similar organic materials. When first encountered, a DC 15 Perception check can be made to avoid them entirely. If the check fails, the ear seekers have contacted the creature and move toward any warm place on the creature (favoring places such as the ears) in which to lay their eggs. Once an ear seeker enters a warm place, it lays 2d8 eggs before dying. In 4d6 hours, the eggs hatch and the larvae devour the surrounding flesh, dealing Constitution damage to the host each hour thereafter. At Constitution 0, the host dies and ear seekers crawl out to find a new host. A remove disease spell kills all ear seekers and any unhatched eggs.
