Where can I get the Spark Hunter Badge?

Hello there, I'm wondering if you could provide me with some insight on where to acquire the Spark Hunter Badge. I've been hearing about it quite a bit in the gaming community and I'm really interested in obtaining it for myself. Is there a specific level or quest that I need to complete? Perhaps there's a hidden achievement or a particular boss I have to defeat? I'd really appreciate any information you can give me. Thanks in advance!
