Now that there's space, Nancy takes the opportunity to get out of the horrid wagon, slipping past Draco and looping around the creatures - at a safe distance.
There, she begins another spell, gathering a dark power in her hands and hurling it at the nearest of the skum.
Actions
Move down and around - should be able to get to J17 without provoking.
Use 1 Mythic Power for Inspired Spell to cast Touch of Blindness (DC15) at the nearest skum - the one in melee with Coals, though it sounds like that one's nearly dead anyway. Thanks to Divine Reach this is a ranged touch attack, but I still take a -4 for "firing" into melee.
