Myrnil (3.5e Equipment)
From D&D Wiki
Myrnil also referred to as black mithril is a rare formation of mithril, a silvery blue black appearing metal sought after for its light weight and strength. Myrnil due to a change in its composition is lighter than mithril and stronger, though the changes to it are unknown and impossible to reproduce. Found in the deepest depths of mithril veins miles beneath the surface of worlds this metal has earned itself a variety of nicknames. When worked at a forge like steel this wonderous ore transforms into an incredibly lightweight metal stock which is normally reserved for use in armor. More so the material itself is so expensive the wealthiest nobles and Kings are generally the only ones that can afford its price.
Myrnil armor is treated as one category lighter, including dwarven full plate, down to a minimum of light armor. Spell failure is reduced by 20%, Damage reduction of 4/-, maximum Dexterity bonus is increased by 4, and armor check penalties are reduced by 4 to a minimum of zero.
An item made from myrnil weighs one-fourth 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 but does change the ease with which it can be wielded (whether it is light, one-handed, or two-handed). Items not primarily of metal are not meaningfully affected by being partially made of myrnil. (A longsword can be a myrnil weapon, while a scythe cannot be).
Weapons made from myrnil are also very strong allowing them to bypass any hardness less than 15 for objects.
Myrnil has 35 hit points per inch of thickness and hardness 18.
