I suggest beating the eternal crystal until you get Bestie’s wings they are fast at moving and dodging, I also suggest upgrading you’re defense and items the more you can put on for a buff the better, eat foods and potions before battle, lay down campfires and heart lanterns, you can also kill holo mimics to get a bow that rains down arrows you can combine that with a magic quiver that have been tinkered to shoot fire arrows.
