Mithril

Mithril: HP/inch 30; Hardness 15; Cost Weapons or armors fashioned from mithril are always masterwork items as well; the masterwork cost is included in the prices given below.; Weight 1/2 normal; Weight (Longer Wording) An item made from mithril weighs half as much as the same item made from other metals. 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).   Type of Item Item Cost Modifier Light armor +1,000 gp Medium armor +4,000 gp Heavy armor +9,000 gp Shield +1,000 gp Other items +500 gp/lb. Mithril is a very rare silvery, glistening metal that is lighter than steel but just as hard.   When worked like steel, it becomes a wonderful material from which to create armor and is occasionally used for other items as well. Most mithril armors are one category lighter than normal for purposes of movement and other limitations. Heavy armors are treated as medium, and medium armors are treated as light, but light armors are still treated as light. This decrease does not apply to proficiency in wearing the armor. A character wearing mithril full plate must be proficient in wearing heavy armor to avoid adding the armor’s check penalty to all his attack rolls and skill checks that involve moving. Spell failure chances for armors and shields made from mithril are decreased by 10%, maximum Dexterity bonuses are increased by 2, and armor check penalties are decreased by 3 (to a minimum of 0).   Items not primarily of metal are not meaningfully affected by being partially made of mithril. (A longsword can be a mithril weapon, while a quarterstaff cannot.) Mithril weapons count as silver for the purpose of overcoming damage reduction.   Platinum: The rules shown are for the rare item constructed entirely of platinum rather than being platinum-plated. Platinum-plated items quadruple the base cost of weapons and armor and have the same properties as the item the platinum is plating. Items constructed purely of platinum cost 100 times the normal cost for items of their type. platinum items weigh 50% more than typical weapons or armor of their type.   Weapons platinum is often too soft to hold a decent edge, but light weapons that do piercing or slashing damage can be constructed of gold or some nearly platinum alloy. They take a –2 penalty on damage rolls (minimum 1 damage). platinum weapons have a hardness of half their base weapons’ and also have the fragile quality.   Armor platinum can be fashioned into light or medium metal armor. The softness and the weight of the metal decrease the armor/shield bonus by 2 and increase the armor check penalty by 2. platinum armor has a hardness 5 and the fragile quality.
