Smithing

Smithing a mundane item (any non-magical armor or weapon) requires 1.5x the item’s weight in metal ingots and the same amount of straps used to repair the item normally. Creating any item requires proficiency with a tool unless otherwise stated. Metal armors require the blacksmithing proficiency and checks are made with Strength (Athletics). A list at the bottom of this section will detail the exact amount of materials needed to construct these items.

Silvering Weapons
In order to silver a weapon the smith requires half the weapon's weight in silver. A DC20 check must be made to silver any melee weapon and a DC14 is made to silver any ammunition. Ammunition may be silvered in 'bunches' of 10 at a time. On a natural 1 the silver is wasted and the process must be redone.

Mithril
Creating weapons or armor made from Mithril increases the DC by 2. Additionally, forging Mithril items requires an advanced forge.

Adamantine
Creating weapons or armor from Adamantine increases the DC by 10. Additionally forging Adamantine items requires a nearby lava flow. It also triples the downtime required to forge such an item. Each day spent forging an item from this material the smith makes a DC 18 Constitution saving throw. If they fail they take a level of exhaustion. If the item is not worked on for two days in a row the material is scrap metal and no longer maintains its adamantine qualities. Multiple smiths can work on the same Adamantine item.

Mastercraft Items
Creating a mastercrafted weapon (any +1 weapon) raises the DC by 5. Creating any mastercrafted armor (any +1 armor) raises the DC by 10. This raising of the DC stacks with other specialty crafts such as Adamantine or Mithril crafting. These items are not considered magical in nature and thus do not ignore non-magical resistances and can be destroyed in the same manner as normal mundane items.

Forge Items
Forge items are required for the manufacturing of items through Blacksmithing. These items can be purchased from NPCs if the DM says one such item is available. Otherwise they must be built or found.
