@13org Legs primarily, but general ability to move and respond to stimuli. Think of it as a simulated spinal injury - whatever is scariest to her. The attack will have two stages of effect - a major, severe effect, until she's out of his 'range' or his concentration is seriously disrupted, and then more minor effects like stiffness of limbs, pain, loss of coordination, until an hour or two have passed. Fortunately, Adrion-Outta-Nowhere is going to stun him enough to break the major effects, and allow the party to escape.
Although Aura's gotta fuck him up a bit first.
Btw, any Inquisitor is more than capable of using attacks like this on entire groups of people at once. The main reason Cunningham hasn't is because the Heavens' Eyes are
so far under orders to bring the team in alive and mostly functional. That is, at some point, going to change.
