The number of things that had happened was more than anyone had expected. Awakening a new skill was something that normally happened through harsh training and the consumption of materials. Clark was questioning it greatly while he watched Ralph be taken away while the rest of his team followed.
However, the more Clark's mind worked the more he began to understand. Ralph and his molten boar had been absorbing and purifying metals for hours on end to train, he truly wanted to become a blacksmith to get ahead of others and challenge him. Therefore, Ralph's control and his boar's control of energy had become much more sensitive.
That was enough to activate any skills that were dormant between them. The molten release had sent great amounts of energy to Ralph causing his body damage but also multiplying his strength and basic fighting capabilities. That was how he easily crushed opponents he had struggled with just seconds ago. It was also damaging to the molten boar though.
