I would get 300-500 chlorophyte bullets, if you cant use chlorophyte bullets, then farm ichor and make ichor bullets. Use chlorophyte armor, or hallowed armor. Also, I prefer the clockwork assault rifle because as you know, it fires three shots at a time, but the megashark would work, it would just be a little more difficult. Don’t forget potions. You could also use a few of the temple traps just for extra damage.
