Kallikantzaros

The Kallikantzaroi are a species of particularly mischievous members of the goblin family that originally hail from Greece, but have now spread worldwide.

Appearance
Kallikantzaroi tend to look like normal goblins, however, they tend to have brownish, bark-like skin, icy-blue eyes, and green, pine needle-like hair all over their bodies. This hair is often matted with snow during the winter months.

Behavior

Powers

 * Enhanced smell: Kallikantzaroi are able to detect specific beasts, beings, object, places, and substances, locate their origins, and even track, using nothing but their sense of smell.
 * Cold immunity: Being creatures of the winter, kallikantzaroi are able to withstand the effects of cold.
 * Ice manipulation: Being creatures of winter, kallikantzaroi are able to create and control the element of ice.

Weaknesses
Kallikantzaroi tend to share their weaknesses with their fellow goblinoids, however, they do have a weakness that is unique to their species.
 * Burning shoes: Due to their highly enhanced senses of smell, one can drive away the kallikantzaroi by lighting a fire and burning their smelly shoes.
