Master of the Forge

Prerequisite: Dwarf
Your time as a blacksmith and ancient heritage, you gain the following:

• You can create masterwork weapons and armor when forging an item. A masterwork item costs five times as much as an ordinary item of its type and has the following properties, unless it is a magical item.
  • Masterwork Weapon. You have +1 on attack rolls made with a masterwork weapon.
  • Masterwork Armor. Light masterwork armor is hardened and gains +1 AC. Medium masterwork armor does not produce as much noise, its wearer does not have disadvantage on Stealth rolls. Heavy masterwork armor is properly weighted, and grants advantage to its wearer on checks and saves made to avoid being knocked prone, or to resist being pushed.
