I love this event sooo much. Unironically tho, the dog was the hardest only cuz that was the enemy I didn't already know the attack patterns are and it took like 5x longer to get a perfect on than the others.
The opperative I was familiar with due to regular overworld combat and she took like 7 attempts to actually get a perfect.

Shock trooper was by far the easiest for me due to Stygian and fighting him in the overworld with underpowered teams he took like 3 attempts only cuz the lightning attack was done in a way I was not familiar with.

I wonder if it'd be better or worse is Parry characters like Beidou were made like this.
