Earth's Flame

A rift from the earth opening 10 feet in front of you in a unblocked space, flames born of magma and steam rising up and incasing the raw metals the world itself gave. Burning away all impurities in the raw metals in a 5ft by 5ft(Only 1 and a half feet tall) range, the metals become pure and whole, left in ingots, as if hours in the forge have been spent refining them all.

Only works on common metals pulled from the lightest parts of the earth at the 2nd level, copper, iron, and mithril. For each spell slot higher then the 2nd you cast this from, the zone grows by half foot on each side, the height growing by a quarter of a foot. The metals being left with a shiny polish and adamantine refinement becomes available at the 3rd.

As you cast from the soul of the earth, the earthly father would only let this spell be crafted with a clear head and intent to craft and not fight, if a enemy was struck by the flames of this spell, they would not suffer burns, instead, they would gain a temporary +1 to their attack if they had a metal sword.
