Whatever Nancy did, it doesn't seem to have had that much impact. Continuing to act on instinct more than anything, she begins another chant. Though noticeably different, the dark, infernal words are just as unsettling to hear, as Nancy points at a nearby Skum and attempts to exert her will upon it.
Actions
Spend 1 Mythic Power to cast Murderous Command (DC 15) on a nearby Skum, probably O8 but whatever's left alive really.
Nancy's difficult terrain should be gone by now I think.
