Devi's Charm
Things were becoming a lot more interesting as the forge spirit moved around the master blacksmith. They were amazed by the sheer amount of techniques being used to heat the specific parts of the soul silver as he worked.
Some times he used a small tube to force heat toward one specific aspect of the metal. Other times, he used a small dropper to add oils and other materials to cool the thinner pieces of metal to alter the way that it was settling.
When he began to use the energy crystals, the forge spirit was the one to control the flow of energy through the master blacksmith's hammer.
This was done by forcing the fire energy and the spiritual energy that it could naturally channel to act as a buffer. Then the metal energy was boosted so that the charm being forged would take on a specific strength. It was a wonder that the skills they were witnessing were possible in the first place.
