Been banging my head against this well over 150 times. I have learned this fight well for the first phase. I am going to go over everything I know.
Again, I'm a Bear. This is the same for everyone in the basics, but I don't know everyone. I have NOT beaten it, but I'm getting close to getting through P1
As a bear, if you have the legendary wrists, this should be a cake walk for you. If you don't have them, I think we can still do it. Cause I don't have them, and I think I can get there. My best is 12%. That's one burst away. If you happen to be lucky enough to have that legendary, you can stand outside the purple and you never have to go in except to interrupt and you get the happy task of building rage the whole time. And for that, you get pretty much an easy win.
If you don't, here's what we do!
902 Bear. The legendaries I do have are Sephuz's and the Prydaz Neck. Sephuz really doesn't help much, but every once in a while I go faster. Yay me. The neck, same thing, just absobs such a little amount, but I got nothing better, so there you have it. I've been eathing fireball food... whatever that's called... Fishbrul Special. Yeah, I'm full of technical terms.
I open the fight shifting into bear at the last possible second, he won't pull until you want him to. I prepot a potion of prolonged power and I begin to moon fire. When doing this the fireballs help me smack him just a bit more. While hitting him I'm staying out of the purple. He'll cast a few of his Mind Rends, I think about 4 or so, sometimes more sometimes less. One eyeball usually pops up right before he casts his first drain soul. When that first drain soul comes up I skull bash and hit the crap out of him. However you do that is up to you. After I get 3 stacks I start heading out hoping to not get the fourth becuase it's easier to manage. I'd rather live more than hit him harder. I usually face the eyeball that is up and moon fire it on the way out or after I got out. 2 of them kills those after the dot is applied. Then I wait to gather the adds. I have found that unlike most of the videos I can indeed use an orb almost each time a group comes out. If I don't have to, I won't. But, if I have to I'm not going to be shy about it. Just hit it and move on. If the adds are casting and the boss is draining life, I'm hopping on an orb. That's just a drain life I can't use for a burst, it happens and I just continue.
Here's the thing I learned today. You can... I say CAN use the infernals to build rage. Be careful becuase you gotta hit them on the way by or they will punt you.
The biggest challenge here is not being able to use normal bear things. Iron Fur is SOOO part of who I am and without it I take so much more damage. I want that up when the adds rush in or their initial hit will take me out. I frenzied regeneration when after they smack me and gain most of it back. I'm sparing about FR. I like to keep it in my pocket and use the orbs more.
Hope this little bit helps.
As for P2, you're on your own for now.
I've got about 99 more attempts before this thing closes down. Happy werebear-ing.

Taking notes as I progress. - Important to note, it takes 100 Nethershards and you do take durability loss.
This is for all tanks. I'm a bear
AS A CAT IF YOU STUN HIM TO START THE FIGHT BEFORE THE PURPLE COMES OUT THERE IS NOT PURPLE!
That doesn't work anymore.
Do not stand in purple circle - removes health for a stacking debuff that lasts a few seconds
Stare at Eyes, they do a knock back - can moonfire them but not hit them with anything
Interrupt Drain life - You have a few seconds of it casting, so you can finish off the adds but you don't have long
Pick up adds as they come in - they do a Nether Storm - interrupt that with Velen's yellow ball, this will heal you, interrupt and disorient everything
Infernal does a knock back as well called smash, can just be side stepped. - He also gets smaller somehow. I think it's from kiting.
There is some luck to be had with velen's placement of the heals orb. He has put it in the purple, which isn't so bad, but he may cast it right on top of you and you then use it when you don't want to.
Here's what I'm doing... Stealing ideas from anywhere I can find them
Stun Boss to start, he won't cast his purple circle (I'm going stealth cat to do it)
Fight the boss
Cannot melee the eyes, but try to kill them with some sort of shot (moonfire for me) because they will stop you from moving right later.
Use the yellow orb when needed to heal and stun.
NOT EASY
