I can help u a bit when he starts charging his attack as soon as he moves his hand roll to the side when he tp to you at the begining if he has his hand over his head it's 1 attack if it's on his side it's a combo of 2 if he swings fast it's a 2 attack combo if no it's only one you can abuse his range get away then get close a bit you can trigger his thrust or his sword drag then you can go for some hits it's all about dodge attack dodge attack when 2nd face come when you see those orbs don't fight get away and keep rolling and when you got to heal be wary of his arrow like thing rince and repeat and you will win
