T0 pinnacle - king in the mists ( edited....T1 was wrong labeling also missleading title)

I am farming T12 maps now. Found an audience.
Now I am kind of stuck with that boss.
Have not really enough dmg. But was fully ok for T12.
Can get hit by one of his projectiles in the first phase. Can survive one frog also. Thats it. Rest insta kill.
Can get to phase 2 every time. Takes a while, but ok.

Second phase he just blows me up. Maybe I miss something here. But it is surely not obvious then.

Really?

Audience is rare. And even though I can try him over and over, they made it impossible without chaos res at cap regardless the dmg you do.

For all the good content you just need over the top dmg and res cap, else not intended.
Im not sitting here and be like, ok lets farm another 50 rituals for one audience, to keep it until I trivialized all content.

Nobody can realistically beat this game by just playing through it. You have to do strange stuff over and over. And it does not make any sense.
You need to know where the imbalances of the game are to navigate through it.
Once, I have done and beaten a pinnacle boss, there are still 3 stages they can get harder.
Now it just looks like they want to get rid of the people that actually want to play their game.

Another wall. I dont get it. No loot anyways but getting baited into bricking your build by speccing into single target.

The more I play, the less I understand the policy. Better said the less fun I have with it.
