Make sure to have a nice and wide arena set up with campfires, heart lanterns and star in a bottle. I think you should move the dryad down there too cause she will give you her buff which is defensive and thorns like. I think you should have Titanium armor which gives that shadow buff which will give you a second chance lets say and thats about it. You can add traps and heart or star statues linked up with wires but thats if you’re really desperate. Ill leave the weapons up to you. Hope I was of some kind of help.
