Modron Brass

Modron brass is an extremely rare metal only found exclusively in the bodies and manifested weaponry of modrons. It is harder than any known metal and impervious to nicks and scratches. Though artificers and alchemists have attempted to replicate it for centuries, production of modron brass on the Material Plane is not yet technologically possible by any scientific or magical means.

Properties

Material Characteristics

Modron brass looks similar to ordinary brass, though any reflections on its surface are muted and smoothed. It seems to form exclusively in smooth planes and curves, with no variation or flaw. It cannot be further polished or dulled and does not patina over time.

Physical & Chemical Properties

Modron brass is neither warm nor cold to the touch, but always seems to be the exact temperature of one's fingertips. When licked, there is a slight tingling sensation on the tongue, but otherwise a distinct lack of flavor. It does not react with any other known substance, nor can it adhere to anything except via the use of Sovereign Glue.

Origin & Source

Modron brass is only found in two places: the bodies of modrons and the weapons. Modrons are grown in an orchard in Arcadia and already made of brass when formed. Each time a squadron of modrons crosses the boundaries of a plane, they are able to manifest a single weapon with which to defend themselves, if they are not already wielding one. These weapons range from crude dagger-like stakes wielded by monodrons to long, jointed flails that lock in perfectly with the five arms of a pentadron.
Since modrons' bodies are incorruptible and dissolve into water vapor upon the modron's death, modron brass weapons are the only consistent source of the metal that can be possessed and studied by mortals.

Life & Expiration

It is unknown if modron brass can decay. Modrons' metallic bodies dissolve into water vapor after their seventeen-year-long march. No weapon made of modron brass has been observed decaying in a similar manner or sustaining damage of any kind; however, these weapons never stay in mortal hands for very long. Pentadrons (and likely any theoretical higher-order modrons) are able to sense the presence of modron brass anywhere in the multiverse, and always seek it out when it makes its way into unsanctioned hands. They will fight to the death to repossess the weapon, and cannot be dissuaded from doing so by any means.

Modron Brass Weapons

All weapons made of modron brass are +1 magical weapons that cannot be broken by any means short of a Wish spell. On a hit, the weapon always deals the average amount of damage for its weapon type (rounded down), as do any special attack effects attached to the weapon (such as Sneak Attack). A modron brass weapon can strike targets on the Ethereal Plane from the Material Plane and vice versa. Creatures with a chaotic alignment have disadvantage with all attack rolls made by a modron brass weapon and cannot benefit from any relevant weapon proficiencies. Each day that the modron brass weapon remains in the same location or the same person's possession, there is a cumulative 1% chance that a pentodron will appear within 10 feet of the weapon and attempt to repossess it by any possible means.
