Acid Slugs

Description
Acid Slugs are basically huge slugs. What makes them dangerous, their name already says. They attack any being they sense near them them with a strong, poisonus acid, which can destroy weapons and armor and cause horrible burns on the skin. Acid slugs however are very suspictible to fire, and a lit torch is most times already enough to destroy them.

Acid slugs are only found in dungeons, caves and swamps.

Lore
''Not to be mistaken for the common Slimes of Britannia, the Slugs of the Abyss are gelatinous, amorphous entities. Their extremely small and limited minds are entirely taken up with an insatiable curiosity, and so Slugs are certain to follow any motion they detect. Fortunately for explorers, Slugs have no eyes or ears, and therefore miss much that occurs around them. Of the two varieties of Slug found locally, the Flesh Slug - notable for its pale fleshy color - is the most common and least dangerous. We are not certain if these creatures intend to bite their victims, or if their offensive actions are accidents of their constant writhing. Certainly, no warrior of any experience need fear these pitiful beasts. However, beware the greenish Acid Slug. Though only a little larger than the Flesh Slug, the Acid Slug secretes a noxious vapor which sometimes intoxicates its foes. Despite its fearsome name, this Slug is not poisonous - merely inedible.''
