The Exogorth, known colloquially as the Space Slug, is a gigantic species of toothed gastropod. They are silicon-based lifeforms that survive in the Vacuum of space by making their homes in the caverns and craters of asteroids. They fed on the minerals of asteroids, various stellar energy fields, and Mynocks (Another silicon-based lifeform). The average adult Space Slug grows to about 10 meters in length, but some slugs are known to continuously grow to sizes that rivaled Capital Ships in sheer bulk, with some weighing over a million kilograms.

Abilities Edit

Devour: If an Exogorth hits with it's Bite attack against a Colossal or smaller opponent, it can automatically make a Grapple check at its full bonus as a Free Action. If the Grapple check is successful, the Exogorth can begin Devouring it's target.

The creature being Devoured takes 1d8+10 points of damage each round at the start of its turn, before it takes any actions. When the creature reaches 0 Hit Points, it is swallowed by the Exogorth and continues to take 1d6 points of Acid damage each round at the start of its turn. This Acid damage ignores Damage Reduction and is also applied to all materials, be they organic or inorganic.

Space-Dwelling: Exogorths are silicon-based life forms that take no damage from exposure to Vacuum. However, they take the same damage from being in a planetary atmosphere that ordinary life forms take from being in a Vacuum.
