Belly of the Forge was the most obvious of them. He could use it to eat things. It was even more efficient than his Vampire Lord Frame was as converting things into his direct Stamina, so much so that it could even directly increase his Free Stat potential and Free Stats in the right circumstances.
What was more interesting to Grey were these other abilities that he hadn't seen just yet.
Hide of the Forge was the Body Resistance Ability for good reason. It was similar to the Metal Body Skill he had had in the past, but far more comprehensive. While he could build out the defenses of his body with raw materials and metals, he didn't have to do that alone.
