This... Is a boss battle? This early? Kudos, Atlus. At least you made this fight easy as all hell... So, basically, during this fight you take on about 5 golems, easily dispatched by Rasche and Rina, and Roland and Althea. And you fight Josie, who has Dark Pierce. Nothing to really worry about at this point. Oh, and to make this battle easier, Atlus decided "Hey, I know. Let's put Steiner in this battle too!" So you have a Lv. 11 Steiner, tearing through level 2s and 3s. Don't bother going to the right side with anyone but Rina, however. Steiner can easily 2-shot anything (1-shot with Critical sometimes.) and takes next to no damage from the Golems. He does have Rusty Rain, so watch out for characters like Rasche and Rina who can suffer heavily from that.
