Gas Spore (CR 4)

Gas Spore (Infestation, Plant [Fungus])
CR 4

XP 1,200
Infestation, Plant (fungus)

From a distance, the gas spore is likely to be mistaken for an eye tyrant (DC 30 Perception check), using its mimicry to lure would-be victims to their doom. The gas spore has a fly speed of 10 feet with average maneuverability.

When a gas spore encounters a living creature, it injects poisonous rhizomes into the foe if that opponent fails a Fortitude save. Each day thereafter, an infected creature must succeed on a Fortitude save or take Constitution damage. At Constitution 0, the victim dies and 2d4 gas spores emerge from its body. A remove disease spell cast on affected creature before it dies destroys the rhizomes and prevents any further Constitution damage.

If a gas spore is struck for a single point of damage, it explodes in a violent blast of gas that deals 6d6 points of damage to all creatures within a 30-foot radius (DC 15 Reflex save for half damage).
