When an Evolved, Scamper, or Gastgeber dies, they have a 20% chance to leave behind a small area effect cloud that lasts for 10 seconds and inflicts Mycelium Infection for 2 seconds at amplifier 1. When this occurs, any Infected, Evolved, Hyper Evolved, Experiments, Bairns, Scampers, and Gastgebers within a 60x60x60 block wide range (centered on the location of death) will be alerted to come investigate the area.
