Special Abilities
Spore Cloud (Ex) As a standard action, tulgorth can release a cloud of spores in a 10-foot cube in front of itself.

Transformative Disease: Spore Cloud—inhaled; save DC Fort 17; onset 1d3 days; frequency 1/day; effect 1d4 Str damage and 1d4 Con damage; cure 2 consecutive saves. The save DC is Constitution-based

If a diseased creature dies from the infection, it is reborn in 1d4 rounds a tulgorth.
Root to Spot (Ex) A tulgorth can root itself to the ground and begin feeding on plants in a 30-foot radius as a standard action. All plant life in the area dies within 1d6 rounds. Other plant creatures within this radius suffer 1d3 points of damage per round.

A rooted tulgorth gains a +2 bonus to Strength, a +4 bonus to Constitution, and fast healing 1. A rooted tulgorth cannot move from its spot (though it can otherwise act normally), and must take a move action to uproot itself.

Tulgorths feed on the earth itself, driving their shoulder-vines into the ground and draining the life from nearby plants, leaving only circles of blackened earth. As a tulgorth drains the land, worms and insects often escape from the cracked soil, finding a new home in the tulgorth’s body. As tulgorths mature and ingest more life, their colors become deeper and more vibrant.

Tulgorths propagate their species by transforming other creatures. Creatures who come in contact with the tulgorth’s spores become infected. The resulting infection can cause severe skin irritation, shortness of breath, and nausea. An infected creature dies its corpse becomes the central body mass of a newborn tulgorth.

On Porphyra
The destructive corruption caused by the tulgorth is seem by both Native and Landed Porphyrans as further evidence of Mâl’s influence spreading across the land. Tulgorths though originally from the Forest of Gora have spread as far west as the Great Green.
