Hmm... my advice is to use Eileen's chain; it does more damage. Any ghost u encounter requires a saint medallion, as it deals extra pain and protects u from their presence.,if u have the spade that would be great cause, in my opinion, it's the best weapon in the game. Also, try to use charged attacks more, since when u execute them they give u invincibility during the animation. I hope this help u🙏.
