Jade, a magical material (A to Z Challenge, J)12 April, 2016
In the Sea of Stars, jade is prized both for its beauty and for its innate magic. That is it is easily treatable, either through magic or alchemy, to make it as hard as steel allows it to be shaped into weapons as well as hard-wearing jewelry and other useful objects. Traditional alchemists especially prize tools and bowls shaped from magically hardened jade.
The most important property of weapons made from jade is their effectiveness against ghosts and other forms of returned dead, making jade weapons prized among ghost hunters and spirit slayers.
Jade is often worked into protective amulets, such as those against ghosts, but rarely into to armor though such is extremely effective at defeating the attack of unliving beings.
For those with the wealth to build such thing, Jade serves as a barrier that ghosts and other spirit beings cannot pass through and ghost cages and traps are usually made of this material.
Jade armors can only be made into medium or heavy armor made of scales or plates of jade and only weight three quarters of what their metal equivalent would. The wearer gains damage reduction 5 against damage inflicted by ghosts, spirits and other undead (or effects that mimic such), Spell failure chances for armors and shields made from jade are decreased by 10%, maximum Dexterity bonuses are increased by 1, and armor check penalties are decreased by 2 (with a minimum of 0).
Weapons made from Jade are always of masterwork quality and they ignore the incorporality of ghost and spirits, against corporal undead, they ignore 5 points of damage reduction.
For base Jade items, the cost is:
HP/inch 30; Hardness 10; Cost Weapons or armors fashioned from Jade are always masterwork items as well; the masterwork cost is included in the prices given; Weight An item made from Jade weighs three-quarters as much as the same item made from metal. In the case of weapons, this lighter weight does not change a weapon’s size category or the ease with which it can be wielded (whether it is light, one-handed, or two-handed).
Notes: While Legends of the Five Rings treats jade as a magical material and Exalted goes overboard on magic jade (as it does on everything else), my primary inspiration for this is the Ghost comic book.
And look what was just posted on Tower of the Archmage, The Jade Knives.
