Microscopic Mycetic Spore
Clouds of Microscopic Mycetic Spores are used to blanket a planet during the latter days of a Tyranid planetary assimilation. These spores have a threefold purpose[1]:
- To accelerate plant growth; this helps in reclamation of organic materials in the soil.
- To poison plant and animal life, making it useless as a food source; this weakens resistance.
- To break down cells to help in digestion by the Hive Fleet.
