An interesting note: you don't need to use bind to fight this boss at all. When I was battling him, I would hold a charged nature shot until he let out some of his bombs, get him off the ceiling with the nature shot, and let his bomb hit me to make it explode. Since I had the healing leeches from elsewhere in the cave, I could just avoid his bombs and heal up between doing that. If you have the jelly costume, you don't even need to do that.
Kinda masochistic, but as long as you have healing leeches or the jelly costume, you never have to eat again.
