Metal Slime Lore

A mass of strange metallic sludge that is typically found either alone or, very rarely, in a pack called a glop. They don’t seem to eat, sleep or do anything except wander. Many have assumed a powerful wizard animated mass amounts of metal to form these slimes. Metal slimes are mostly found in mountainous regions within caverns or tunnels or in aquatic areas such as sunken ships or coral reefs.

Appearance. Despite being called a slime, a metal slime is smooth to the touch and does not have any mucus. The metal slime is one single mass of liquefied metal which does not leave any residue in its wake.

Hunted. The metal slimes are often a valued encounter by adventurers. A metal slimes remains can be used to craft metal slime armor or weapons. Crafting such items is a time consuming and difficult process that only the most experienced and knowledgeable smiths would attempt. Due to this, the value of this creature to such a smith is quite high.

Cowardly. The metal slime has an overactive sense of self preservation and sees any other creature as a threat to its life. Because of this, metal slimes are often near tiny cracks and crevices in walls or floors that they use as escape routes. Due to this it is incredibly hard to slay a metal slime.

King Metal Slime. Occasionally one can find a truly massive and marvelous metal slime. This is called a king metal slime. More formidable and dangerous than the lesser metal slime but just as cowardly. The remains of a king could craft multiple weapons and armors easily.

Slime Nature. A metal slime doesn’t require air, food, drink, or sleep.
