the furnace will be used for flamemetal ore aswell as whatever deep north ore will be for certain. then both smelters can smelt 3 types of ore. makes sense. balance as all things should be.

ashlands wont add an entirely new smelter. wouldnt make sense at all.

ashlands will instead add the runetable. this will allow some of the new weapons to change thier elemental property. fire/poisen/lighting where shown.
