You might be able to save a few seconds if you got really lucky with short invincibility phases..
Sudden Rush would slightly speed up landing the first shot but wouldn’t do anything after that. I won’t be trying this again though. Unfortunately this fight just comes down to pure RNG and there’s a lot of random things that can waste a lot time.
Hades can instantly darkness or invincible dash after his shield drops.. Which he does almost every fight. The rock enemies he summons can also completely screw you over, and the amount of time his invincibility last is really inconsistent. It’s impossible to time a hit on the last phase because his invincibilty randomly last way longer than the shield animation, and the amount of time he stays in his shield is ALSO random.. and he can glitch out and just continue attacking for a while when his shield is up.

I still one shotted everything with Calisthenics Programs 2 on.. Trippy Flare seems a little overpowered.
