who the fuck created infernum calamitas

I have 185 attempts on this shitty boss im so tired of it I have a headache because of thos fucking boss. I can like 50% of the time make it to the desperation phase and then get past the first 2 moves but by the time they are done I have like 10 fucking health because the infernum devs are fucking stupid and made everything do more than half my health so I basically have to no hit to have a good chance. I am using asgardian aegis, drews wings, dark sun ring, nucleogenesis, the sponge, chalice of the blood god, and draedons heart all menacing. I am using perditus with cosmic immaterizlier, lilies of finality, mirror of kalandra, and cadaverous carrion.
