In the extended play example on p156, after the MoC makes his grenade move and Marie takes harm, she sets off her pain-wave projector and does 1 harm area loud to Church Head, Whackoff, and Plover.  She "does it" but she doesn't have to roll for it.  Is that a mistake or did the MoC decide in this instance that she doesn't have to roll for it because he was already looking at them through crosshairs?  She's normally need some kind for roll there, yeah?
