Ability Interferer

Ability Interferer is a special block added by. It is a creative-mode-only block, and can disable the usage of any in a certain area. By default it is toggled off, and when toggled on, it has a 21x21x21 cubic interference range, centred at itself. Do note that once it is placed in the world, only the placer can control the block, making it a convenient admin tool in a server.
