Stench (aura, olfactory) 40 feet. A creature entering the aura must succeed at a DC 20 Fortitude save or be sickened 1 (plus slowed 1 for the same duration on a critical failure). On a success, the creature is temporarily immune to the sickened and slowed effects of this stench for 1 hour. Regardless of the save, while within the aura, creatures take a -2 circumstance penalty to saves against diseases. An otyugh's stench is due to the offal and refuse that it wallows in, so cleaning the creature thoroughly (with create water and sufficient scrubbing, for example) deactivates the aura, while a sufficiently plugged nose allows an individual to avoid exposure to the stench.

Reposition The otyugh attempts to move all creatures that it has grabbed into other spaces within the reach of its tentacles, rolling a single Athletics check and comparing the result against each creature's Fortitude DC. On a failure, the creature remains in place, and on a critical failure, the creature is no longer grabbed.

Lords of sewers, ditches, and landfills, otyughs are filthy monstrosities that stomp about on three massive legs in search of tasty garbage and refuse. Using two barbed tentacles to grasp and tear, guided by a third with a proliferation of eyes at the end, the otyugh has perfectly adapted to life in its cramped, disgusting environment, where it uses its appendages to see into tight spaces and grasp hidden prey.
Most assume that otyughs originally evolved in swamps and moved into sewers as civilization encroached on their natural habitats. True or not, they are now one of the larger predators in those dank environs. Otyughs are territorial, but they have been known to form loose collectives, even giving each other important-sounding titles like " king of offal” and " duchess of slime” to indicate their rank and station in their sludgy underworld beneath the streets.
Those who run across an otyugh might be surprised to hear it speak, shouting at intruders to leave its putrid home or demanding tribute in the form of trash or other prizes of dubious nature.
Otyughs happily wallow in and consume the garbage of other creatures, making them an efficient (and ecological) disposal system for those bold enough to try such a tack. The problem, though, as such otyugh keepers soon realize, is supplying enough refuse to keep the nigh-insatiable otyugh from wandering off from its miasmic kennel.
