>>715597807 (OP)I played on hard.The systems were pretty easy.
With the monkey brush dude you basically use the skill that is buffed at the moment.
Stains were easy for me since I basically had a defined order of actions as Lune no matter what I faced.
Stances were the best imo, you basically want to get to the purple one and then launch a big attack.
I don't like forestall and I almost never used the scythe bitch because she requires you to go "weak action->strong action->weak action" etc which was way too slow in hard for my taste. Maybe she's actually good, I didn't really delve too much into her movepool.
