Viridantine (Greenmetal)

Viridantine is a lustrous, emerald-colored metal beloved by the Elves and Fairy Folk of Panzoasia. Also called “Greenmetal”, it occurs in long veins underground, particularly beneath forested land. While Viridantine can be forged like iron, the preferred way to craft items from it involves placing a small piece of the metal in a stone mold packed with organic material (typically leaves and forest detritus, but sometimes meat), and sealing the mold with wet clay. The metal will “eat” and replace the organic matter as it grows, eventually filling the mold. The item is then removed, and polished (or sharpened). The process is not fast – growing a longsword from Greenmetal requires a full year – but it allows Elves and Fairy Folk to create metal objects without stoking fires in the forest. An object made of Viridantine is about strong as steel, and weighs the same. Viridantine does have a major disadvantage, whoever – objects made from it must be “fed” once a week, or they will deteriorate like untreated wood. A Viridantine item can be fed in three ways: by partially burying it in earth and exposing the unburied portion to sunlight from morning to dusk, by completely burying it in rich soil for a day and a night, or by rubbing the object with a pint of blood (which will be absorbed by the metal). Another weakness of Greenmetal is that it is particularly vulnerable to acid, dissolving twice as fast as iron or steel.

If an object made of Greenmetal is planted in soil and left alone, it will grow out of its shape and sprout branches and roots, eventually resembling a small and leafless tree. If buried, the object will become the seed for a new vein of Viridantine. Monsters such as Black Puddings and Grey Oozes enjoy the taste of Viridantine and will seek it out – as will Purple Worms. Since it is not ferrous, however, Viridantine is immune to attack from Rust Monsters.

As long as a Viridantine mine is not completely depleted, the remaining metal will regrow at the rate of 1 cubic foot per thousand years. If the vein is regularly tended and fed with decomposing organic matter, then the rate of regeneration is increased to 1 cubic foot per century.

Value: The same as ordinary steel.


This bizarre material is lusterless and dead black in color. Unlike normal metal, which tends be cool to the touch, Calidurum is always warm. Found in Fiery Purgatory and the deepest parts of the Underworld, Calidurum is hardened by extreme heat, but softens and turns purplish in ice-cold water. It melts completely and glows bright blue at -50 Fahrenheit (or -45 Celsius). Since it is actually improved by extreme temperatures that can melt ordinary metals, it is widely employed by creatures such as Saganic Salamanders and Fire Giants. They maintain special wet forges, where the Calidurum is melted in cold crucibles carved from Lithic Ice. Working Calidurum is considered extremely hazardous by the Salamanders and Fire Giants, and the “Coldsmiths” who do it are hailed for their extreme courage.

If a Calidurum object contacts a Wall of Ice (or is hit by White Dragon Breath), its owner must Save versus Breath Weapon to prevent the object from being ruined. On the other hand, a weapon made of Calidurum gains +1 to hit and damage for every 200 degrees Fahrenheit to which it is heated (maximum +5). Calidurum armor similarly heated confers a +1 bonus to AC per 200 degrees (if the occupant can withstand such temperatures). At temperatures sufficient to melt iron, Calidurum is harder than Adamant. Conversely, Calidurum weapons are -1 to hit and damage in cold temperatures, and Calidurum armor becomes -1 to AC.

Tools made of Calidurum are prized by those Dwarven smiths that work Adamant and Admantine Steel.

Value: 1,000 gp per pound.
