I am not a smart man and am playing the DLC for the first time in NG++.
Anyway, I got to the end and...I don't know what to do about the Orphan of Kos. The first part is fine, but the second part is RIDICULOUS. I don't even know when to get a hit in, and the damage is insane. Pls advise.
I was in this boat last week. Now I'm in the Laurence boat, but I'm at that point in phase 2 where I know what to do, I just need to calm down and execute (pun intended!).
For Orphan phase 2, I kept medium distance and dodged for the most part. There were a few attacks that I just never got the dodge timing down and ate them every time. He does something like a three ground slam and then a jump slam - yep, I'm eating those hits.
I don't know how you handled phase 1, but I got good at baiting out the jump and then punishing with a backstab. You can still do that in phase 2, but it's less common. He has some openings after attacks and that's where I punished. Recognizing them and avoiding them just took repetition. I will say I beat phase 2 much quicker than I "beat" phase 1.
I preferred to fight out in the water, and when he calls down lighting I beat on him a little bit if I was close enough.
Laurence and Orphan, to me, were about first learning to dodge what they throw at you, and then slowly working in safe hits where you can. When I beat Orphan I was getting to the second phase consistently without taking damage. I worked in parries where I could but often times screwed up the timing on them. Backstabs were where it's at for me.
I was around level 120 on NG+ for what it's worth. Threaded Cane +10 on Orphan. Skill/Arcane build.
