Forged Destiny [Book 5: Ch. 10]

It wasn't a pattern I `Engraved` onto the metal this time, but rather a line scored into it. And then another line, and another, and another, and over and over on the exact same spot until the metal was worn and pushed aside, creating a deep chasm. It wasn't a Skill I could really hope to use in melee since it took a good ten minutes on each tower, but it did work. I could even push it through connected metal, allowing me to touch the cladding on the front and trace the pattern over a hundred feet above me – so long as there was enough metal to work with.
