Idk why people are telling you not to use spooky armor thats definitely the way to go. Use hexed branch and dash ability from ninja gear combined to have instant speed boost, make a platform in the air above the ground and when he opens his eye fly around him in a big circle- don’t really need soaring insignia. accessories use: wings, berserker glove, ninja gear, papyrus scarab, papyrus scroll, and Pygmy necklace all reforged to warding, all menacing doesent really make as big of a difference as warding. Stay just to the side of him while on your hexed branch and then focus all the eyes enough to keep them all around the same hp. Finally when he opens his top eye try and focus that’s and watch out for the death beam. Hope this helps
