I am convinced that the Nightmare King Grimm uppercut attack is designed specifically to make me suffer.

It feels impossible. The dash and uppercut are fine, extremely easy to dodge actually, you just need to be able to use dash yourself and have shade cloak.

The fireballs, however, feel like they have been designed by the devil specifically to make me atone for my sins. They fire in random directions, are too fast to be able to humanly react to, and they still deal 2 damage (4 on ascended, the difficulty i am currently trying to beat NKG on) with every hit. The shadow cloak is guaranteed to be on recharge because the only reliable way to dodge the dash-uppercut is by using dash. The only thing you can do to avoid these fireballs is pray to your deity of choice that they will decide to spare you for this attack and not hit you. And NKG spams that attack. He uses it all the time. These fireballs appear in my dreams. I cannot escape them. I am sure that after i die i will go to hell, and my punishment will be having to dodge these god forbidden fireballs made of pure malice, hatred and sadism for all of eternity.

I need help with dodging them.
