The irridescent boarhemoth is an enormous beast, with a heavy, stocky body reaching 10' long and a wingspan exceeding 20' wide.  They favor dense forests, jungles, swamps, and overgrown ruins.  At night, they glow with a greenish luminescence (which can be channeled into a destructive beam).

Voracious scavengers, boarhemoths devour plant matter, carrion, and even the occasional live morsel...and they find Mutant Plants to be a particular delicacy (meaning they favor Plant PCs as targets, and will utilize the Dive maneuver to carry them off to be devoured at leisure).

Boarhemoths breed in the spring, and lay 1d8 eggs.  There is a 25% chance that any boarhemoth encountered will be accompanied by 1d2+2 caterpigs.

When stretched end to end, caterpigs stand about 2' tall and reach lengths of 15'-20' long; however, their unusual looping gait makes their midsections reach heights of 6'-8'.  Voracious herbivores, they dwell amongst the giant flowers and leafy treetops of  overgrown forests and jungles.  Caterpigs also infest derelict farms and food processing plants.

A caterpig spends a year in its infant form, but then spins a cocoon in the winter...whereupon it emerges in the spring as a fearsome boarhemoth. 

There is a 25% chance that any wild group of 3 or more caterpigs will be accompanied by a boarhemoth.

Some enterprising settlements gather boarhemoth eggs so as to raise the hatchlings in captivity, as certain herbal combinations and supplements keep caterpigs in their larval state indefinitely.  Once their venom sacs are removed, domesticated caterpigs not only provide succulent meat, but also a fine silk prized by weavers and traders.

Mutations:  Dermal Poison Slime (Class 4)
