Silver

In the world of Dragonslayers RPG, silver is magic. Creatures of unnatural origin are repulsed by silver's appearance and pained by its touch. Because silver is softer than iron, silver weapons are expensive and difficult to craft, and silver armor is nearly unheard of.

Silver Ammunition (Bundle) (Rare): Attacks with this piece of ammunition ignore the immunity or resistance to mundane damage of certain specified Monstrosities, Outsiders, and Undead.

Silver Weapon (Rare): Attacks with this weapon ignore the immunity or resistance to mundane damage of certain specified Monstrosities, Outsiders, and Undead.

Silver Armor (Very Rare): While you wear this armor, you have advantage on all tests against being charmedfrightened, or possessed by a Monstrosity, Outsider, or Undead. In addition, a Fighting test made by a Monstrosity, Outsider, or Undead against you has disadvantage if the creature is adjacent to you.

Unnatural Creatures Using Silver Equipment: A Monstrosity, Outsider, or Undead has disadvantage on Fighting tests with a silver weapon (but not with a piece of silver ammunition). A Monstrosity, Outsider, or Undead has disadvantage on all tests while wearing silver armor.
