Critical hits for Redrum?

[MattPieti]

Is there a specific requirement for getting critical hits other than just attacking with the enemy standing in a red tile? Or just a time when it wouldn't count for a critical, like if the enemy is turned the other way or something? I definitely got more than 5 hits in red tiles in my last battle and the trophy didn't pop. I also didn't get the "critical hit confirmed" popup (or whatever it says) at all during the battle. Having a lot of trouble getting this one and I'm near the end of my first playthrough.

 

Edit: I won the battle and I'm fairly sure my characters were not blinded. This also wasn't the first battle where I tried for 5+ criticals.

Edit 2: Ok, I just got it after many, many battles where I definitely hit in the red zone more than 5 times. The only thing I can think of that might have been different about this one is that I did it exactly 5 times. If that's not it, I have no idea what the problem was before.
