Recommend a challenge run

Just finished hunting for all achievements on expert and can’t wait to go back for more gameplay.

I have a couple of ideas for challenge runs as an average skill gamer but can’t decide which one to embark on first. Please let me know if you’ve tried one of these before or would recommend any of them.

-glass cannon builds: I heavily relied on shields and HP/defense stacking so doing a low HP and defense run to really focus on dodging/parrying sounds like a challenge

-permadeath: if a character dies, they’re permanently dead. So no auto death pictos and will have to focus on survivability

-solo character: self explanatory. Stack much buffs as you can on one character and run through the game

-speedrun superboss%

Or if you have any other fun ideas, please let me know! Thank you!
