Following the first topic about "Fast Switching shield" and from the discovery @tackthumb find (in the comments of the second link, below)
There is two weapons you can switch between them to create a "breaking loop", the first as buff for your party, and the second as most powerful CC effect for enemies with shield or meidum/heavy armor. Of course, some other weapons could be great for fast switching character, but these ones are certainly the most impressives.
