Phoenix Logs/Flood Units/Blisters

Incubation chambers.

Non-sentient animals or corpses not harnessed for combat forms are seeded

with Flood cells and transformed into infection form-filled sacs. These diseased

growths are one of the most pernicious aspects of the Flood, and a single spore

could potentially transform an entire planet's biosphere into quivering masses of:

diseased mucus and bile if left unchecked.

Blisters "hatch" infection forms when disturbed. Destroying them at a distance

is almost always the best option.
