Context: I'm currently writing a story where I'm giving unconventional and otherwise impractical battle weapons more spotlight. So I am currently contemplating making my main character a boomerang(s) wielding warrior of legend by the end of his journey/life. "Retriever" Boomerangs (Boomerang that always returns to the user even after hitting through some currently unspecified method) would then be my main character's signature weaponry.
The battle boomerang, also known as boomerang weapon is a common trope in works of fiction but I can't help but wonder how effective would such a weapon really be? And for that matter how useful or useless/hazardous would a bladed variant of this weapon be? I have the impression that the wooden boomerang is the superior and more practice weapon of the two (wooden vs bladed).
So this character of mine is ideally going to be equipped with upwards of 10 boomerangs + cable wires (to be used as a whip of sort or for tying, strangling) + throwing knives + smoke/powder pellets + backup sword + shield.
Anyway what possible fighting techniques could a character who wields almost exclusively boomerangs possibly use?
An idea I had initially was to have my character throw Boomerangs at his opponents to distract them and then quickly close the distance between himself and his opponents in order to go for the kill. However I am currently trying to find other fighting styles or techniques for my character, techniques that could also harness the boomerangs ability to return to it's user.
Thanks for help!
