Inferno Deep Pit Smoke from Mid
Stand in the corner near bench, where the broom is. Aim where the top of the balcony floor intersects with the yellow wall.
As the video shows, make sure to aim at the top of the balcony floor, and NOT at the decorative bracket that holds up the balcony. Otherwise your smoke will land on the roof.
