*Spoilers ahead*
Act 4, Arx. Sewer fight.
With Isbeil.
During the fight Justinia can assist you, but she's not considered an "ally". So all attacks from you that normally ignore allies will affect her, and vice versa.
Problem is, Justinia doesn't give a whit if you're in the way of her AoE attacks. So if she hits a party member, and they have Retribution, she will take reflected damage, and THIS MAKES HER HOSTILE, forcing you to fight her too. Running away then coming back doesn't clear the hostile flag.
It's not such a big deal, all in all, but I don't understand how an issue like this was never noticed and fixed. It's so freaking obvious and is a bother when it happens.
