Magic Nullification

Magic Nullification (魔法無効) is an Intrinsic Skill of the True Giants. It negates Magic which was thought to be impossible. It is said that it's possessed only by the greater giant race, though this is unclear on if this refers to just the True Giants or if there are other Giants who possess it.

Abilities
It negates the effects of nearly all types of Magic by interfering with Spiritrons and canceling them out making them an Anti-Magic Guard (絶対魔法防御). This leaves the user vulnerable to purely physical attacks and emission-type attacks that work off of a principle different from most magic like Nihility Magic.
