I don't think you need all of that. He is a generally hard boss though, so... I'd say just get some gold armor and max out your health. I still don't have a lights bane, and I've beaten him at least twice. Make sure you are above ground. My first time fighting him, I was at the sphere location in my mine. It was pretty freakin tough to fight him there. Still pretty easy though. Good luck, hope this helps!
