The entire fight is a RNG shitshow with high variety in damage.
P1: Before first Senti Ult, I do an additional normal attack, swapping to chains and do the combo. This gives significant more SP for later in the run. The rest is straigt forward. But it is disgusting how different the HP of the big guy can be once the rotation is done... ranges from oneshot to an entire bar left.
Transition: The goal is to position Senti in a way that Proms QTE hits the cube - ideally while HoS Ult is still up.
P2: The excess SP from P1 comes in handy here. No need to cast another chains combo. But this is another bullshit phase. You can do giga damage and overshoot by a lot... or not. Regardless of using chains or a bonk. I took the "believe that damage is good" approach.
