Parasect is known to infest large trees en masse and drain nutrients from the lower trunk and roots. When an infested tree dies, they move onto another tree all at once. The larger the mushroom on its back grows, the stronger the mushroom spores it scatters. A mushroom grown larger than the host’s body controls Parasect. It scatters poisonous spores.
