Weapons: Some creatures that are resistant or immune to nonmagical weapons are suceptible to silvered weaponry.

Silvered weaponry deal an additonal 1d4 damage to Lycanthropes, Shape-Changers and Undead that are not immune to the weapon's non-magical properties. If the creature is immune it takes the weapon's damage as normal.

 

Armor: Silvered armors are much more rare and costly, but grant benefits of their own. A creature that is suceptible to silvered weaponry has, in turn, disadvantage on attempts to grapple, restrain or otherwise physically incapacitate the wearer.

Weapons: Some creatures that are resistant or immune to nonmagical weapons are suceptible to adamantine weaponry.

When you attack an object with an Adamantine weapon, it scores a critical hit. Against constructs, Adamantine weapons deal an additional 1d4 damage.

Additionally, Adamantine weaponrs count as being silvered.

  

Armor: Adamantine armor require the majority of the armor to be made of adamantine, as such, leather and studded leather armors, and robes cannot be made adamantine.

Mithral, Mythril or Mithril is an extremely rare, durable and lightweight metal, requiring deep devotion by even the grandest of armorsmiths.

 

Mithral Weaponry: Lightweight and durable; Weapons made from Mithral have the unique property of being half the weight of their standard variants. Weapons with the Heavy property lose this property, but otherwise any other requirements apply (such as two-handed). Weapons without the Heavy property, but do not have the Light property, instead gain the Light property.

 

Mithral Armors: A mithral chain shirt or breastplate can be worn under normal clothes or robes. If the armor normally imposes disadvantage on Dexterity (Stealth) checks or has a Strength requirement, the mithral version of the armor doesn't.

Requiring the skill of a master craftsman, masterwork weapons are hard to come by, often found in only the grandest cities, or sometimes as the result of a quest to seek out an artisan capable of such complex work.

Masterwork weapons fall into one of several categories: Honed Edge, Perfectly Balanced, or Flawless. Masterwork weapons are primarily bladed weapons. Masterwork weapons if enchanted, permanently lose their masterwork bonuses.

 

Honed Edge: Masterwork weapons crafted to hurt. They provide a +1 bonus to damage rolls. (Keen, Honed)
Price: Honed Weapons Tend to be around 500gp above standard rates

 

Balanced: Masterwork weapons crafted to be easier to wield. They provide a +1 bonus to attack rolls.  (ie. Balanced)

Price: Balanced Weapons Tend to be around 500gp above standard rates

 

Flawless:  Masterwork weapons that are the pinnacle of craftsmanship. They provide a +1 bonus to attack and damage rolls. Flawless weapons are typically named by the craftsman. (Flawless, Peerless)

Price: Flawless Weapons Tend to be at least 1500gp above standard rates

 

Enchanting: Many Masterwork weapons are capable of being enchanted, but in such cases, the masterwork is ruined throught he enchanting process. Masterwork weapons made of mithril or adamantine or another incredible materials, are carefully crafted to accommodate enchanting. Peerless weapons may be Honed, Balanced or Flawless, and are considered the pinnacle of craftsmanship. Masterwork weapons made of Mithril or Adamantine still run the risk of having their masterwork statuses lost, but have the chance to maintain them. Any lesser materials will always lose their masterwork.

 

Damaging the weapon: Masterwork weapons are still weapons, and if they are not cared for properly, can be damaged, even if they were peerless enchanted weapons.
When you roll a natural 1 on your attack roll, you roll a second d20, on a second natural 1, the weapon is damaged and loses its masterwork. Even if repaired by a skilled smith, or the mending spell, it does not retain its attack or damage bonus.

Darksteel Equipment: Also known as Star Metal and Meteoric Iron, equipment forged from Darksteel is Extremely rare and is said to be forged from the souls of fallen stars. Darksteel is the embodiment of the Heavens, and said to grant one the strength of Gods. Darksteel Equipment is believed by some to be Adamantine by another name, but some sources have described it as malleable like iron, forged like steel, and as hard as Adamantine.

It is believed that the last Meteor that fell to Aeion did so 300 years ago in the Southern Continent of Dherkokh.

Night-Indestructible: Darksteel Equipment is nigh-indestructible once forged, and retain its shape even after the most testing of trials. Darksteel Equipment is impervious to destruction by most means aside from high-level spells.

 

Unenchantable: Once fully forged and quenched, Darksteel becomes nearly incapable of becoming enchanted, except by wizards of the absolute highest calibre. The 4 Kingdoms of Heclea have learned that Artificers are one such group of mages capable of performing this feat. By Fabricating the enchanting catalyst together with the raw Darksteel, a weapon can be made, perfectly ready for enchanting by a powerful Mage.
