For all of us that hate the sound when Dart Intent gets a new stack or gets refreshed, this makes those sounds go away by making the game, play blank files instead of the supposed files.
This isn't just for warlocks its also for those that receive the DI buff.
This doesn't change any Blizzard files instead it creates a directory with this sounds files in it, and the game will play these instead of the new ones.
