Without Snow or your own link for active guidance you aren't able to pinpoint any likely targets. You don't really notice anything of importance at first, people are realizing they are in a bad situation and are scrambling to take cover or flee.
Then the spirit materializes near O'Conner and blows a cloud of brown fumes at him.
Noxious Breath
Type: P • Action: Complex • Range: special • Duration: Instant
The critter can project a nauseating stench to incapacitate victims.
Treat it as an inhalation vector toxin attack (Speed: Immediate, Power:
critter’s Magic (FORCE 5), Effect: Stun damage, nausea; see p. 254). Armor does
not help resist this damage, but respiratory protection will (see the
Toxin Protection table, p. 254). This blast of breath extends in a cone
out to (Body) meters, and can catch up to two targets who are within
one meter of each other
Inhalation toxins must be inhaled by the target and are applied as
an aerosol spray or gas. A target wearing a gas mask, chemical seal, or
using an activated cyberware internal air tank (p. 342) is immune to
its effects. Chemical protection gives a bonus equal to its rating to the
Toxin Resistance Test.
Immediate means the Effect is applied at the end of the Combat
Turn the victim is exposed to the toxin.
Nausea: Nausea is a catch-all term that covers pain, panic, vomiting,
double vision, and other toxin effects. If the Power of an attack
after the Toxin Resistance Test exceeds the target’s Willpower, she is
incapacitated (unable to take any actions) with vomiting and dizziness
for 3 Combat Turns. Whether or not a character is incapacitated,
nausea doubles all of a character’s wound modifiers for 10 minutes. A
nauseated character with 3 boxes of damage (a –1 wound modifier),
for example, suffers –2 dice on all tests instead.
