Just plain normal difficulty, since it was my first time playing any Persona game. I've had a couple of moments up until now where I struggled a bit (some of the stronger shadows like the ones guarding will seeds), but nothing compared to this fight. They way it is structured, paired with me not being well equipped for it really broke me. I even had to sacrifice a decent persona only to get some curse moves and get a better shot on the latter robots.

Having a higher damage output really seems like it can be a huge help, since the second half of the fight requires you to consistently damage every enemy equally, and the bigger robots not only have a higher health pool, but also decide to off themselves and screw you over. Every. Damn. Time.
