Just looked at the trophies since I have it on PC. You have to beat Hell with every character, level a char to 99, and also level a hardcore char to 99.
You have to do 5000+ Hell Baal runs on Players 3 (if you're single player) to get from 98 to 99 and NEVER DIE since it's hardcore.
So yeah good luck with that Shine lol
edit: I guess you could save scum to protect from dying but still a major time investment
