This elemental has to be present during the entire duration of the smithing process. Weapons made of Adamantine cost 10x their base price.

Mithral and Adamantine and Magic Enchantments
Both Mithral and Adamantine equipment can be made into +1,+2, or +3 enchanted equipment as well. This must be done as part of the original crafting process and has the same reagent as regular +X equipment. Making a +X magic item out of Mithral or Adamantine increases the rarity of that item by 1 step and as such all costs but the reagent. If you are making a +X weapon you must pay the 6x or 10x cost in addition to the magic item cost.
