Yeah, it's the Clair Obscur fight. Basically you equip level 31 Contorso on Verso, your standard offensive pictos, inverted picto, last stand pictos, and machine gun pictos. Auto death the rest of your team. He goes in alone and wrecks shop. Takes about 10 seconds per fight. And if you're using Contorso, instead of 5 lumina, you get 10. Every loop took me just under 90 seconds so you can farm 100 in about 15 minutes. I ended up farming like 225. After, everyone was between 225 and 260 for lumina.
As far as Simon, he's a challenge. Machine gun didn't do anything for me. At least my build. But I haven't looked up any builds so no idea if mine was optimized. 100% sure it wasn't. All I'll say for Simon is try to go in blind and do it that way before you start looking things up. The only thing I looked up for Simon was googling things like "Why is Simon such bullshit" and from that, I gleaned the basic strategy based on people mentioning certain pictos to use. I was pissed at that point so wanted to see what other people were feeling about him. But even with that knowledge, I was getting my ass kicked. I literally reset all pictos on everyone and carefully selected everything just for that fight. After I did that, then I finally merc'd him the next round. My Maelle is a nuke but she's a mini nuke. She absolutely couldn't one-shot Simon with how I had her set up but she one-shots everyone else.
