5 basic attacks,
all 3 starting heals,
one of the trap boxes from area 1 for def up,
one of the cheerleader plants from area 2 for atk up,
area 3 boss for aoe dmg,
2 of the cleaner android girls for single target dmg and paralyze chance,
2 kotatsu snails for more intensive heals,
area 4 boss for aoe dmg and freeze chance,
squid for aoe dmg and blind,
area 5 boss for high single target dmg and mp reduction,
and 2 of the cute maid succubi for good single target dmg and freeze chance.
Basically try to stay at relatively full health, since that makes the qte's way easier to deal with. Use your cards mostly to try to keep the arms debuffed when they are up, if you end up blinding or freezing the boss as well that's a plus but you are mostly trying to keep the arms out of the fight without focusing them. For dmg, you want to wait until you can drop your 100 tp attck without any atk down debuff, or better yet when you have atk up from cheer plant. DO NOT focus the hands since he can resummon them at any time effectively wasting any effort to kill them, and he AUTOMATICALLY resummons or heals them once his hp reaches certain thresholds. Don't be afraid to go full turtle mode if you get def down, keep your hp up, clear statuses, and be ready to dodge qte's. Beyond that, don't drop alot of cards for dmg unless you have attack up, and come into the fight with a full inventory of healing and mp items, it's a long fight.
