GIANT SLUG

Giant slugs are pale gray. Their underbelly is dead white.

Giant slugs dwell away from light, preferring the depths of dungeons and similar places. Giant slugs are able to eat substances like wood or burrow through very hard earth using their rasp-like tongues. Although they are a great bulk, giant slugs are able to squeeze through very narrow or low openings, for they have no bones to prohibit such alteration of shape. They have thick, rubbery hide, and their tremendous power allows them to break down doors with ease.

Although able to bite with effect, the major weapon of these creatures is a highly corrosive acid saliva which they are able to spit with considerable accuracy at great distances. Normal range is 6", with a basic 50% chance of striking their target. For every 1" the range is lessened the base chance of hitting is increased 10%; ranges over 6" decrease the probability of hitting by 10%. 

Fortunately, the giant slug is always inaccurate on its first attack, and there is only a 10% chance of its hitting its target on the first spitting of acid; once the range is then determined, second and following attacks are at normal probabilities.

Because of their size and structure, these beasts are not affected by blunt weapons, so they must be attacked by sharp-edged ones or magically.

As they are of great size, these creatures can sometimes be caught in a narrow corridor where they are unable to turn, and if they are then attacked from behind they can often be slain without loss to the attackers.
