Fighting Perfectheart as Sunny and friends

Well... that wasn't so bad. Sunny's "Allegro" deals 15% of the target's Max Heart 3 times, and never misses. So as long as he always has over 200 Heart, you can just use Encore and Allegro to win the fight without too much struggle. In case you were wondering, I modded the game to let me change the party's names so I could name them after childhood friends that they reminded me of, and edited the battle text so that the game actually used the party's names. That's why their names are different. Party set up: AUBREY (JEN) CHARM - WEDDING RING Aubrey is the only one able to actually damage Perfectheart with her Homerun attack, so the idea was to have her start off Happy to let her act sooner. SUNNY (LIAM) Level 10* WEAPON - VIOLIN CHARM - HECTOR JR The Faraway Town cast can't actually perform Follow ups, so the Energy stat is essentially always at 10 after Perfectheart uses more than one of her several full party attacks. KEL (MATTHEW) CHARM - FLOWER CROWN One of Perfectheart's attacks deals exactly 175 damage to everyone, so in order for Kel to actually get to do anything he needs to have at least 200 Heart, which is a problem considering he only gets 130. HERO (RYAN) CHARM - ROSE HAIRCLIP I like Hero but he sucks for this. He's way too slow and way too weak. I figured that maybe if all his stats were boosted he might be a little more useful, but his Speed is still too low and Defense is largely ignored by Perfectheart. My plan was to lower Perfectheart's Speed to 30% and make Aubrey, Kel, and Hero all Ecstatic as quickly as possible, and then to keep healing the party with Kel and Hero while Aubrey used Homerun and Sunny used Allegro. Unfortunately that strategy doesn't really work because Perfectheart isn't that merciful. I was probably doomed if I hadn't already done so much damage. *Sunny has his own unique level up stat curves, whereas the others revert down to their Head Space stats after reaching level 2, so I modded everyone but Sunny to gain 0% of the experience earned in fights. Despite the Faraway group having their max levels set to 1 in the database, they would normally still be able to level up for some reason.
