Sound Imitation (Ex): Mongrelmen can imitate the sounds made by any monster or creature they have encountered. They can imitate the sounds of monsters with special vocal attacks, but they cannot in any way duplicate the special powers or damage done by those attacks. Detecting the ruse requires a successful Will save (DC 14).

Fear (Su): 20 feet, a mongrelman can also use its power of mimicry to combine or alter the sounds it knows how to make; creating ghastly wails, snarls, hoots, and roars. Any creature within 20 feet hearing the sound must succeed at a Will save (DC 11) or be shaken for 1d4 rounds. This aspect of the mimicking power only works if the mongrelman is concealed. Mongrelmen rely on this ability to scare off unwanted intruders and pesky wilderness travelers.

Mongrelmen receive a +8 racial bonus to Hide and Sleight of Hand checks.

A mongrelman performs acts of violence only in self-defense or (in the case of slaves) on the orders of their masters; free mongrelmen do not hesitate to kill anyone they believe threatens their community. They prefer to avoid contact with other creatures except in times of great need, when they try to steal what they require (food, tools, etc.).

The Mongrelman first appeared in the Monster Manual II (Gary Gygax, 1983).
