Inscription

The powers of this inscription are still shrouded in mystery. When applied to an object, it increases its durability by many times, even if the components of said objects are not fused together. For example, Killua, whose superhuman strength allows him to easily twist any iron box open, was unable to warp Ging's box in the slightest. However, any object bearing the inscription will break immediately if it comes in contact with Nen. According to Killua, this is because the inscription has similar powers to Nen.
