Thousand Fangs Below Monsters:
Alien creatures of aberrant origin, Vemeraks are true demons of the Darklands. While they are crude, aggressive, and unintelligent, they are also deeply religious, worshiping alien gods who have no place in the worlds of men. They are just as likely to eat you alive as they are to scatter your organs across a crude shrine. Their otherworldly composition makes them resilient to most forms of attack. Because of their ties to the earth, they are immune to acid, poison and electricity.
Vemeraks are covered with an alien fungus with magic draining properties. The fungus grants the Vemerak with spell resistance, and as it movies, creates a cloud of anti-magic. These creatures can spray a line of caustic stomach acid. This acid dissolves all organic matter in seconds, and then evaporates upon contact with air forming a cloud. Those who inhale this gas will be nauseated from the fumes.
The most devastating ability of a Vemerak stems from their tentacles.
