SPECIAL ABILITIES
Accelerate Plague (Su) Anyone bitten by a rat demon must
immediately make saving throws against any disease it is
currently inflcted with, as if 1 day had passed. If the disease
is still in its onset period, the bite of the rat demon causes
it to skip the rest of the onset period, requiring the creature
to save or suffer the effects. Saves made due to this ability
do not count toward curing the disease, nor do failures count
when determining consecutive saves.
Aura of Sickness (Ex) All creatures, except rats, demons, and
other similar creatures, within 10 feet of a rat demon take
a –2 penalty on Fortitude saving throws. This penalty is not
included in the save DCs of the rat demon’s abilities.
Cloud of Disease (Su) Once per day, a rat demon can call forth
a cloud of disease. This acts as a fog cloud, but any creature
in the cloud must save once per turn or be affected by
contagion, gaining a disease of the rat demon’s choice (this
choice is made only once, it is the same disease for all the
creatures in the cloud). A successful DC 17 Fortitude saving
throw negates this effect, but a new saving throw must be
attempted each round a creature is exposed to the cloud. The
cloud lasts for 1 minute. The save DC is Constitution-based.
See the Bonekeep Maladies sidebar for a list of diseases.
Disease (Ex) flesh rot: Bite—injury; save Fort DC 17; onset
immediate (failing the fist save causes the effect);
frequency 1/day; effect 1d3 Con damage and 1d3
Cha damage; cure 2 consecutive saves. The save DC is
Constitution-based. Creatures that take damage from this
disease develop a hazy fim over their eyes and take a –4
penalty on Perception skill checks as long as the damage
remains. The save DC is Constitution-based.
Keen Attacks (Ex) The bite and claw attacks from a rat demon
are very deadly and threaten a critical hit on a 19–20.
