I agree a bit with above, but also ... why the title said "MUSIC box" ? I just don't see the point xD (reference to dishonored ?)
In the video game Dishonored, you play the bodyguard of an Empress of an alternate reality Europe. After her death, your framing for her death, your escape from jail, and your inheriting magical powers from a strange being, you set out to set things right. One of the enemies in the game are soldiers belonging to a church who oppose the stranger who gave you your powers. One of their weapons against followers of the stranger are music boxes that produce a tone that neutralizes magic.
I'm in agreement with others in this thread. It seems needlessly complicated and would most likely only be used to troll those who prefer to use magic mods rather than industrial mods on multiplayer servers. It also does not seem to fit thematically. Why a music box? Why copy Dishonored? If this idea is implemented, and given the number of vanilla functions and the ungodly number of magic mods it would have to interact with to do so, I highly doubt it will be, it would most likely be some sort of technological device, like a machine that can generate a magic-like energy and feed it out of phase with the magic in the environment to cancel it out.
