A flare is fired, bouncing along the ground until it comes to a stop. Around that location, 15 bombs will start falling from the sky consecutively dealing 7 damage per blast. The bombs drop at an angle, so it will depend on the terrain where they land. The flatter the terrain is, the closer the bombs will land from each other. Unlike Air Strike, the bombs will not destroy terrain.
The third and final tier is where the real change happens. First off, the attack starts dropping the shells like normal, except there are flames that remain on where the shells landed, dealing an additional 2 damage each.
