The smoke bombs go off without a hitch, producing large clouds of smoke, billowing up over wide areas of the city. The flames, however, don't seem to affect the spheres much; a small patch burns for a minute or so, then extinguishes. The fireball attacks, however, draw some attention on him, as one lucky, or, perhaps, unlucky guard spots him and calls it out, trying to alert his companions, though there's only a handful of the guards still in the area, who also happen to be standing between him and the vault's entrance.
