"Ever since the dawn of magic, I had a slight fear that I would be loosing followers to the offensive spells. Initially, I had sought to solve this by having magic require weapons. As you all held that down, I had to find another way. Seeing as the young god seemed to have created a new magic rather simply, it should be trivial for an elder god like me. So I will attempt to make my own magic, one that will be considered a weapon by its user.
Thaumetallurgy.The ability to work metal miracles. Thaumetallugarists (Nicknames will no doubt be given for this craft) are capable of controlling metalwork as if it was their own body. The intent is, of course, more combat oriented than other magics. A swordsman should be able to thrash his sword like a whip, or smack his palm against his enemy's armor, causing spikes to form inwardly. Its use will not be strictly limited to combat, a man could potentially craft a horse or other beast out of metal and ride it about as if it was living, for example. More practically, practitioners should be able to improve their smithing skills, perfecting the metal with their magics. It could potentially be used to replace lost limbs or even more complicated body parts like lungs or even a brain, if the user could manage prolonged spell use without burning out. I think I have outlined enough to get an idea of what it is, without limiting it too much. Is there any necessary steps to make this happen?"
